ITEM 1. BUSINESS

GENERAL DEVELOPMENT OF BUSINESS

STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT

     The statements in this 10-K that relate to future plans, events or
performance are forward-looking statements that involve risks and
uncertainties.  Actual results, events and performance may materially differ.
Readers are cautioned not to place undue reliance on these  forward-looking
statements, which speak only as of the date hereof.   The Company undertakes no
obligation to release publicly the result of any revisions to these forward-
looking statements that may be made to reflect events or circumstances after
the date hereof or to reflect the  occurrence of unanticipated events.

RISK FACTORS

COMPETITIVE ENVIRONMENT.  Coherent encounters aggressive competition in all
areas of its business activity.  Coherent's competitors are numerous, ranging
from some of the world's largest corporations to many relatively small and
highly specialized firms.  Coherent competes primarily on the basis of
technology, performance, price, quality, reliability, distribution, customer
service and support.  To remain competitive, Coherent will be required to
continue to develop new products, periodically enhance its existing products
and compete effectively in the areas described above.

NEW PRODUCT INTRODUCTIONS.  Coherent's future operating results are dependent
on its ability to rapidly develop, manufacture and market technologically
innovative products that meet customers' needs.  In addition, after the
products are developed, Coherent must quickly manufacture such products in
sufficient volumes at acceptable costs to meet demand.  Without the
introduction of new products and product enhancements, Coherent's products are
likely to become technologically obsolete, in which case inventory may be
written off and revenues would be materially and adversely affected.  There can
be no assurance that such new products, if and when introduced, will receive
market acceptance.  However, Coherent anticipates that it will continue to
incur significant research and development expenditures in order to maintain
its competitive position with a continuing flow of innovative, high-quality
products.

INTERNATIONAL SALES.  The Company conducts a significant portion of its
business internationally.  International sales accounted for 55% and 53% of the
Company's sales for fiscal 1997 and 1996, respectively.  The Company expects
that international sales will continue to account for a significant portion of
its net sales in the future.  A significant amount of  these sales occur
through its international subsidiaries, some of which also perform research,
development, manufacturing and service functions.  As a result of the Company's
international sales and operations, it is subject to the risks of conducting
business internationally, such as protective tariffs, import/export controls,
and government takeover of business.   The most common risk is fluctuation  in
foreign exchange rates, which could affect the sales price in local currencies
of the Company's products in foreign markets, as well as the Company's local
costs and expenses of its foreign operations.  The Company uses forward
exchange, currency swap contracts, and other risk management techniques, to
hedge its exposure to currency fluctuations relating to its intercompany
transactions and certain firm foreign currency commitments;  however, its
international subsidiaries remain exposed to the economic risks of foreign
currency fluctuations. There can be no assurance that such factors will not
adversely impact the Company's operations in the future or require the Company
to modify its current business practices.

ASIA-PACIFIC.  Recent economic trends, particularly in the Asia-Pacific
marketplace, have caused a heightened awareness of the impact this portion of
the world's economy can have on the overall economy.  As the Asia-Pacific
market currently represents almost one-third of the worlds buying power and
approximately 25% of Coherent's sales are to this region, changes in this
area's economic growth rate may impact suppliers of product into that market.
While the actual magnitude of the business at risk is 

                               2

<PAGE>

unknown, it is likely that capital spending in this market will decrease 
which could have an adverse impact on Coherent's sales and results of 
operations.

QUARTERLY FLUCTUATIONS IN OPERATING RESULTS.  A variety of factors may cause
period-to-period fluctuations in the operating results of Coherent.  Such
factors include, but are not limited to, product mix, competitive pricing
pressures, material costs, revenue and expenses related to new products and
enhancements of existing product,  as well as delays in customer purchases in
anticipation of the introduction of new products or product enhancements by
Coherent or its competitors.  The majority of Coherent's revenues in each
quarter results from orders received in that quarter.  As a result, Coherent
establishes its production, inventory and operating expenditure levels based on
anticipated revenue levels.  Thus, if sales do not occur when expected,
expenditure levels could be disproportionately high and operating results for
that quarter  and potentially future quarters, would be adversely affected.

VOLATILITY OF STOCK PRICE.  The market price of Coherent's Common Stock may be
affected by quarterly fluctuations in Coherent's operating results,
announcements by Coherent or its competitors of technological innovations or
new product introductions and other factors.  If revenue or earnings in any
quarter fail to meet expectations of the investment community, there could be
an immediate impact on Coherent's stock price.  In addition, the stock market
has from time to time experienced extreme price and volume fluctuations,
particularly among stocks of high technology companies, which, on occasion,
have been unrelated to the operating performance of particular companies.
Factors not directly related to Coherent's performance, such as negative
industry reports or disappointing earnings announcements by publicly traded
competitors, may have an adverse impact on the market price of Coherent's
common stock.  See Item 5., "Market for the Registrant's Common Equity and
Related Stockholder Matters".

PATENTS.  The laser industry is characterized by frequent litigation regarding
patent and other intellectual property rights.   Because patent applications
are maintained in secrecy in the United States until such patents are issued
and are maintained in secrecy for a period of time outside the United States,
the Company can conduct only limited searches to determine whether its
technology infringes any patents or patent applications.  Any claims for patent
infringement could be time-consuming, result in costly litigation,  diversion
of technical and management personnel, cause shipment delays,  require the
Company to develop non-infringing technology or to enter into royalty or
licensing agreements.  Although patent and intellectual property disputes in
the laser industry have often been settled through licensing or similar
arrangements, costs associated with such arrangements may be substantial and
often require the payment of ongoing royalties, which could have a negative
impact on gross margins.  There can be no assurance that necessary licenses
would be available to the Company on satisfactory terms, or that the Company
could redesign its products or processes to avoid infringement, if necessary.
Accordingly, an adverse determination in a judicial or administrative
proceeding or failure to obtain necessary licenses could prevent the Company
from manufacturing and selling some of its products.  This could have a
material adverse effect on the Company's business, results of operations and
financial condition.  Conversely, costly and time consuming litigation may be
necessary to enforce patents issued to the Company, to protect trade secrets or
know-how owned by the Company or to determine the enforceability, scope and
validity of the proprietary rights of others.

GOVERNMENT REGULATION.  The medical devices marketed and manufactured by the
Company are subject to extensive regulation by the FDA and some foreign
governments.  Pursuant to the Federal Food, Drug and Cosmetic Act of 1976, as
amended, and the regulations promulgated thereunder, the FDA regulates the
clinical testing, manufacture, labeling, sale, distribution and promotion of
medical devices.  Before a new device can be introduced into the market, the
manufacturer must obtain market clearance through either the 510(k) premarket
notification process or the lengthier premarket approval ("PMA") application
process.  Compliance with this process is expensive and time-consuming.
Noncompliance with applicable requirements, including good manufacturing
practices ("GMP") can result in, among other things, fines, injunctions, civil
penalties, recall or seizure of products, total or partial suspension of
production, failure of the government to grant premarket clearance or premarket
approval for devices, withdrawal of marketing approvals and criminal
prosecution.  The FDA also has the authority to request 

                               3

<PAGE>

repair, replacement or refund of the cost of any medical device manufactured 
or distributed by the Company.

REIMBURSEMENT.  Approximately half of the Company's medical products are
purchased by doctors, clinics, hospitals and other users, which bill various
third-party payors, such as governmental programs and private insurance plans,
for covered health care services provided to their patients.  Third-party
payors are increasingly scrutinizing whether to cover new products and the
level of reimbursement for covered products used for these health care
services.  While the Company believes that the laser procedures using its
products (except for most aesthetic applications, which comprise approximately
half of the Medical segment's revenue) have generally been reimbursed, payors
may deny coverage and reimbursement for the Company's products if they
determine that the device was not reasonable and necessary for the purpose for
which used, was investigational or not cost-effective.  Failure by doctors,
clinics, hospitals and other users of the Company's products to obtain adequate
reimbursement for use of the Company's products from third-party payors, and/or
changes in government legislation or regulation or in private third-party
payors' policies toward reimbursement for procedures employing the Company's
products could have a material adverse effect on the Company's business,
results of operations and financial condition.  Moreover, the Company is unable
to predict what legislation or regulation, if any, relating to the health care
industry or third-party coverage and reimbursement may be enacted in the
future, or what effect such legislation or regulation may have on the Company.

EARTHQUAKES.  A substantial portion of Coherent's research and development
activities, manufacturing, its corporate headquarters and other critical
business operations are located near major earthquake faults. Operating results
could be materially affected in the event of an earthquake or other natural
disasters.

YEAR 2000 COMPLIANCE.  The Company is aware of the issues associated with the
programming code in existing computer systems as the millennium (year 2000)
approaches.  The "year 2000" problem is pervasive and complex, as virtually
every computer operation will be affected in the same way by the rollover of
the two digit year value to 00.  The issue is whether computer systems will
properly recognize date sensitive information when the year changes to 2000.
Systems that do not properly recognize such information could generate
erroneous  data or cause a system to fail. The Company is utilizing both
internal and external resources to identify, correct or reprogram, and test the
systems for   year 2000 compliance.  It is anticipated that all reprogramming
efforts will be completed by December 31, 1998, allowing adequate time for
testing.  This process includes getting confirmations from the Company's
primary vendors that plans are being developed or are already in place to
address processing of transactions in the year 2000.  However, there can be no
assurance that the systems of other companies on which the Company's systems
rely, will also be converted in a timely manner or that any such failure to
convert by another company would not have an adverse effect on the Company's
systems. Management is in the process of completing its assessment of the year
2000 compliance costs however, based on information to date (excluding the
possible impact of vendor systems) management does not believe that it will
have a material effect on the Company's earnings.

PRODUCT NARRATIVE

MEDICAL

     Coherent's Medical Group (CMG) develops, manufactures and distributes a
broad line of medical laser systems used in ophthalmology, dermatology,
gynecology, plastic surgery,  aesthetic surgery, orthopedics, otolaryngology,
neurological surgery,  urology, podiatry, oncology and other surgical
specialties.  These lasers are designed to improve the quality of patient care
and frequently decrease overall healthcare costs compared to conventional
procedures.  Most of these products also make it possible to perform treatments
in a doctor's office, surgi-centers or outpatient centers in hospitals instead
of requiring patient hospitalization.

     SURGICAL PRODUCTS

     Coherent introduced the first solid state holmium laser, the 
VersaPulse-Registered Trademark-, in 1988.  With its wide variety of fiber 
optic delivery devices, which are much smaller than conventional 
instrumentation, the VersaPulse quickly established itself as a first choice 
for minimally invasive surgery.  Since that time, product enhancements and 
improvements have allowed Coherent to maintain its leadership position.

     In 1993, the VersaPulse Select-TM- was introduced.  This revolutionary
product doubled the holmium laser power available to the arthroscopic surgeon
while reducing the physical size of the system to just half that of previous
models.  The tissue effects allowed cutting, ablation and smoothing of
cartilaginous tissue with minimal bleeding.  An additional effect of precise
collagen shrinkage has emerged as the procedure of choice for joint
instability.

                                6

<PAGE>

     In urology, the VersaPulse Select holmium laser is emerging as a
revolutionary option for lithotripsy.  With the advent in the mid-1990's of
more flexible, miniturized endoscopic devices, all areas of the urinary system
could be accessed, opening the door for new treatment options.  The holmium
laser, coupled with flexible fiber optic delivery devices has proven to be the
most effective lithotrite and the VersaPulse Select is the choice of leading
urologists around the world.

     In 1994, Coherent introduced the VersaPulse Select Dual Wavelength laser
for urology.  For the first time, two complementary laser wavelengths, Holmium
and ND:YAG, were incorporated in one system.  Via single delivery device and
with the touch of a foot pedal, the surgeon could quickly switch from the
precise cutting, ablation and other fragmentation of Holmium to the deep
penetration and coagulation of Nd:YAG.  This combination not only allows
maximal versatility in treating the broadest range of urologic applications but
also provides maximal utilization of the VersaPulse Select within the surgical
arena.

     AESTHETIC PRODUCTS

     Coherent is a leading supplier of lasers to the rapidly growing aesthetic
laser market.  Starting in 1994, with the UltraPulse for treatment of wrinkles,
Coherent has introduced a complete line of innovative laser products for
aesthetic procedures including laser skin resurfacing, cosmetic eyelid surgery,
treatment of tattoos, treatment of pigmented lesions, treatment of vascular
lesions including leg veins, and laser-assisted hair transplant.  In addition,
in November 1997 Coherent became the exclusive distributor for Palomar's laser-
based hair removal products throughout most of the world.

     The UltraPulse 5000C with Computer Pattern Generator is a leading laser
for treatment of wrinkles.  Called laser skin resurfacing, this procedure uses
the unique high energy pulsed output of the UltraPulse laser to produce
precise, controlled and repeatable vaporization of a thin outer layer of skin.
The laser is also widely used for aesthetic incisional procedures including
cosmetic eyelid surgery.  Since its introduction in 1994, it has become one of
the largest selling lasers to aesthetic surgeons for these procedures.

     The UltraFine erbium laser for skin resurfacing  was introduced in August
1997.  This system complements the UltraPulse 5000C, providing  new treatment
capabilities for the aesthetic surgeon.  The UltraPulse remains the laser of
choice for mild to severe wrinkles.  The UltraFine erbium laser extends this
treatment to a new group of patients who require more superficial treatment.
In addition, this laser can be used in concert with the UltraPulse to enhance
the overall therapy.

     In 1996, Coherent introduced the multiwavelength VersaPulse aesthetic
laser.  Featuring four lasers in one box, this product can be used for the
removal of tattoos and treatment of both vascular and pigmented lesions, such
as birthmarks, port wine stains, and "telangiectasias," the unsightly veins of
the legs and face.  Physicians use up to four separate laser systems to achieve
the capabilities offered by a single VersaPulse aesthetic laser.  New laser
technology developed at Coherent allows treatment of lesions containing larger
vessels that often do not respond to conventional lasers.

     The UltraCut incisional scanner for laser-assisted hair transplant was
introduced in October 1997.  Used with the UltraPulse 5000C laser, the UltraCut
laser prepares sites in the scalp to receive hair grafts.  This system, which
has been in clinical trials for over three years, offers a number of advantages
to the hair-transplant surgeon including reduced bleeding, faster procedures
and improved cosmetic results.

     In November 1997, Coherent signed a partnering agreement with Palomar
Medical Technologies for laser-based hair removal systems.  Coherent is the
exclusive distributor for Palomar's laser-based hair removal systems in the
United States, the Far East and most countries in Europe.    Coherent is
responsible for sales, marketing, service, training and education.  Palomar is
responsible for design, development and manufacture of its laser-based hair
removal systems.

     OPHTHALMIC PRODUCTS

     Coherent pioneered the use of lasers in the ophthalmology market segment
27 years ago and is still the global leader.  CMG offers argon and multiple
wavelength lasers for photocoagulation and treatment of retinal disease and
glaucoma.  The Company's Nd:YAG lasers for photodisruption are used for
treatment of secondary cataracts.  Coherent also sells an excimer refractive
surgery system in many countries in the world other than the U.S. for
correction of vision disorders including myopia, hyperopia and astigmatism.

     Coherent's argon photocoagulator was the first such device to achieve
widespread acceptance by the medical community for treatment of diabetic
retinopathy, retinal detachments and glaucoma.  The argon photocoagulator is
also used in treatment of age-related macular degeneration.

     The Ultima-Registered Trademark- 2000 and Novus-Registered Trademark- 2000
photocoagulator product lines utilize a patented "power-on-demand" laser tube
design where power is on only when required for treatment by the physician.
This innovation substantially extends the laser tube life and eliminates the
need for an external water supply.  A broad line of accessories allows these
products to provide Laser Indirect Ophthalmoscopic laser treatment and surgical
endophotocoagulation with Acculite-TM- probes in addition to slit lamp
applications with the LaserLink-TM- Adapter.  The portable design of the Ultima
2000 product line allows the system to be transported to the patient for
treatment in convalescent or retirement care facilities, or used in the
operating room, as well as in intensive care nurseries for retinopathy of
prematurity.

     The Novus Omni-TM-, introduced in fiscal 1994, attains a new level of
compactness, reliability, and flexibility in ophthalmic multi-wavelength
applications.  With instantaneous switching among red, yellow, and green
treatment options, the retinal surgeon can now benefit from the proven
technology improvements in the Novus and Ultima lasers and multiple wavelength
lasers.

     Coherent's Nd:YAG laser photodisruptors are used primarily for posterior
capsulotomies.  These solid-state, Q-switched lasers provide ophthalmologists
with a method for treating secondary cataracts in a non-invasive manner.
Unlike the argon and multiple wavelength lasers used in photocoagulation,
Nd:YAG lasers produce high power pulses as short as ten billionths of a second.
These brief but powerful pulses produce an "optical breakdown" effect which
disrupts (cuts or perforates) the tissue rather than producing a thermal burn.
Nd:YAG lasers are also used for iridotomies, a procedure used in the treatment
of closed angle glaucoma, whereby the laser makes a hole in the iris
facilitating the outflow of fluid trapped in the eye.  This outflow relieves
pressure which, if left untreated, could cause damage to the optic nerve.

     In October  1997, Coherent introduced the next generation EPIC-TM-
ophthalmic laser system which enables the ophthalmologist to perform most laser
treatments with one system.  In December 1997, the Company received government
approval to sell this product. This three-in-one laser incorporates a new clip-
on Nd:YAG laser, a frequency doubled laser and an argon laser.  The EPIC laser
system is a portable laser which adapts to the ophthalmologists existing
examination slit lamp.  Shipments of EPIC will begin in January 1998.

     In 1996, Coherent introduced Selecta 7000, a new Q-switched, frequency
doubled laser for the treatment of glaucoma.  The treatment involves the
selective targeting of trabecular meshwork cells which increases fluid outflow
from the eye.  There are minimal side effects and the treatment called
selective laser trabeculoplasty (SLT) could prove an important advance in
glaucoma therapy.  The procedure is currently investigational in the U.S. with
FDA clearance expected in late 1998.

     In March 1994, Coherent and Herbert Schwind GmbH & Co. KG entered into a
marketing  and sales agreement which gives Coherent the exclusive right to sell
the Keratom-TM- excimer refractive surgery system in many countries of the
world.  This product uses a high energy argon fluoride excimer laser from
Lambda Physik, an 80% owned Coherent subsidiary in Germany,  to obtain a high
quality laser beam that is more uniform, and optical components that are
simpler, more reliable and more durable than 

                                8

<PAGE>

competing machines.  Keratom uses the patented HaloPure-TM- generator to 
provide ultra-pure halogen, as needed from a self-contained, solid-state 
source through a computer controlled chemical reaction.

     The medical laser systems manufactured by Coherent's Medical Group are
subject to regulation and control by the U.S. Food and Drug Administration and
other international regulatory agencies.  See "Impact of Medical Device
Regulations".

     The laser systems manufactured by the Medical Group typically range in
price from $25,000 to $500,000.

ELECTRO-OPTICAL

     Coherent's electro-optical products include lasers and laser systems for
scientific, medical research, micromachining, commercial applications,
precision optics and related accessories.  The principal types of lasers
produced by the Company's Electro-Optical segment are argon and krypton ion,
excimer, carbon dioxide (CO2), liquid dye, Nd:YAG, Titanium:Sapphire
(Ti:Sapphire), diode-pumped solid-state (DPSS), and semiconductor lasers (laser
diodes).  These lasers have a broad range of power and operate in the visible
(V), ultraviolet (UV) and infrared (IR) portions of the electromagnetic
spectrum.  The Company's optics and optical products include special purpose
lenses, mirrors and advanced optical coatings.  Coherent's electro-optical
products are sold for scientific, medical, commercial end users and OEM
applications.

     SCIENTIFIC AND COMMERCIAL GROUP

     The Coherent Laser Group (CLG) and Coherent Lambda Physik (CLP), the
Company's 80% owned subsidiary in Gottingen, Germany, comprise the Scientific
and Commercial Group.

     CLG is headquartered in Santa Clara, California, and is a leading
developer and manufacturer of ion, dye, solid-state Nd:YAG, Ti:Sapphire, DPSS,
diode and CO2 lasers for the scientific, OEM and micromachining markets.  The
lasers sold by CLG are used in basic and applied research in medicine,
chemistry, physics, biology, biochemistry, engineering and forensic sciences,
and in a variety of commercial applications including materials processing,
semiconductor microlithography, stereolithography, interferometric wafer
inspection, reprographics, optical disk manufacturing, analytical
instrumentation, laser light shows, and manufacturing process control.

     In fiscal 1996, CLG changed its organizational structure from a product
line focus to a market focus in order to better serve its customers in their
different market channels.  As a result, two business units were formed:  a
Commercial business unit which focuses on OEM and industrial accounts and a
Scientific business unit focusing on the scientific community.

     In March 1995, the Company  (and ATx Telecom Systems, Inc. (AMOCO)) 
entered into an "Asset Purchase and Sale Agreement" whereby the Company 
purchased certain assets (consisting primarily of patents and technology 
licenses) relating to AMOCO's diode pumped solid-state laser technology.  In 
June 1995, the Company acquired the business and net assets of Adlas GmbH and 
Co. KG (Adlas), in Lubeck, Germany, a manufacturer of CW infrared, green and 
Q-switched lasers whose products  complement the DPSS product line.

     In fiscal 1997, the following important events occurred:  CLG continued to
provide its customers with lasers for a growing range of applications,
especially in the CO2 (i.e., material drilling and marking) and diode-pumped
solid state (DPSS) (i.e., disk texturing) product lines. The Group also
purchased the assets and technology of Micracor, Inc. of Massachusetts to
position CLG for entrance into the telecommunications market. Also, CLG saw
continued strong growth for the Lubeck operation, including shipments of the ZT
laser for the disk texturing market.  With these acquisitions and
aforementioned products, CLG has consolidated its patent position in the DPSS
area, increased its portfolio of product offerings to better address the
commercial and micromachining markets, and has opened up a 

                                9

<PAGE>

manufacturing and service entity in Europe for such products.  The first 
shipments occurred on the Verdi-TM-, a CW diode-pumped solid-state visible 
laser that  provides a compact, high-power, efficient option for many 
scientific and commercial laser applications.

     Coherent's 80% owned subsidiary Coherent Lambda Physik (CLP), develops and
manufactures excimer, DPSS, and tunable lasers including dye lasers and optical
parametric oscillators (OPOs).  These powerful pulsed lasers cover the spectral
range from 157 nm to over 4 um.  Producing UV light   without frequency
conversion techniques, the excimer laser is very efficient,  gaining strong
market share in industrial and medical applications.  The diode-pumped solid-
state developments are driven by the challenge to produce the highest possible
frequency conversion efficiencies and beam quality for UV-power with
outstanding brilliance at 1 kHz.

     All Lambda Physik products are certified with the CE-mark, a prerequisite
for the European market. This is an important milestone of Lambda Physik's
quality program and opens up excellent opportunities in the medical and
industrial marketplace.

     During fiscal 1997, Lambda Physik improved the Novaline-Litho-TM- 248, an
excimer laser for deep ultraviolet (DUV) photolithography systems used in
semiconductor processing, according to customers' needs by significant
reduction of bandwidth and pulse-to-pulse amplitude fluctuation. In parallel,
new Novaline medium and narrow bandwidth models for the more advanced
wavelength of 193 nm were released. There are only three companies with the
technological capability to manufacture DUV excimer lasers at 248 nm for
photolithography systems.  The companies are Cymer, Inc., Coherent Lambda
Physik (CLP) and Komatsu.  Cymer is well ahead of the competition as it has
been focused on this market for the past 10 years and it has a market share in
excess of 90%.  Also in fiscal 1997, the LAMBDA StarLine-TM- family of diode-
pumped YAG lasers was expanded by adding 4 new models with different repetition
rates and energies. These new lasers open a variety of applications ranging
from spectroscopy through LIDAR to hole drilling and micro machining. Lambda
Physik has produced some of the most respected pulsed laser models for
spectroscopy in the world.  The present pulsed dye laser, SCANmate-TM-, and
parametric oscillator, SCANmate OPPO-TM-, set a new standard in the scientific
world in narrow-linewidth tunable light sources for high resolution
spectroscopy in the range from 189 nm to over 4 um.

     The lasers and laser systems produced by CLG, with the exception of
semiconductor lasers, typically range in price from $10,000 to $250,000.

     The lasers and laser systems produced by CLP typically range in price from
$10,000 to $450,000.

     SEMICONDUCTOR GROUP

     In July 1995, the Company acquired the laser diode operations of Uniphase
Corporation.  With this acquisition, the Company added  high power
semiconductor laser diodes with wavelength emissions from 670 to 980 nanometers
to its product lines.  These laser diodes are key components for the Company's
growing segment of diode-pumped laser products, thereby reducing its dependence
on outside vendors.  Laser diodes are also widely used in medical, printing,
OEM instrumentation, remote sensing, and machine vision industries. In December
1996,  the Company acquired 80% of the outstanding capital stock of Tutcore OY,
Ltd., and an option to acquire the remaining 20% in five years.  Tutcore is
located in Tampere, Finland and is the leading manufacturer of aluminum-free
semiconductor wafers that are incorporated into laser diodes.  In February
1997, CLG completed construction of a 10,000 square foot clean room facility to
support the diode business.  In August 1997, the Company formed a separate
group which is now known as Coherent Semiconductor Group; previously, such
operations were a part of CLG.  This group consists of the Santa Clara laser
diode division as well as the Tutcore division located in Tampere, Finland.

     Semiconductor laser diode prices range from $500 to $3,000.

                                10

COMPONENTS GROUP

     Coherent's Auburn Group (CAG) manufactures optics, thin film coatings for
high-performance laser optics, laser accessories and electro-optical components
for the Company as well as other manufacturers.  CAG also distributes products,
manufactured by others,  through its catalog business.

     Optics and thin film coatings, which consist of mirrors and lenses used
for imaging and directing a laser beam, are used in the Company's own laser
products, in low-loss coated optics for OEMs and other commercial applications.
During fiscal 1997, the Optics Division introduced a number of specialized
coatings for OEM's developing systems in the UV spectral region.  Applications
include photolithography systems being built for the next generation
semiconductor "fabs"; micromachining and photorefractive keratotomy.  In
England, the Leicester operations developed a revolutionary new system for
manufacturing graded interference filters which have use in commercial lighting
systems and analytical instrumentation devices.  Patents have been applied for
on the technology.

     CAG also designs and manufactures laser measurement instruments and
accessories that are used to measure and maximize the performance of laser
systems.  In the fourth quarter of fiscal 1997, the LaserCheck was introduced,
a complete laser power measurement system that is the size of a penlight.

     Also during fiscal 1997, the Auburn Group purchased the assets and
operations of Ealing Electro-Optics (Ealing) based in Watford, England and its
U.S. subsidiary located in Holliston, Massachusetts from The 600 Group plc.
Ealing is a recognized leader in the design and manufacture of precision
optical assemblies as well as complete lens and thermal imaging test systems.
The Ealing "Gold" catalog sells over 5,000 components to the photonics
industry. This acquisition gives CAG  the capability to do higher level electro-
optic assemblies in Watford, and adds a complete worldwide catalog operation
for sale of all the Group's products.

     Products made by CAG typically range in price from $500 to $50,000 and are
sold through CAG's field and telemarketing salesforce, the aforementioned
catalog and through  an international network of independent distributors as
well as other Coherent sales groups.

MARKETING, DISTRIBUTION AND CUSTOMER SERVICE & SUPPORT

     Coherent markets its products domestically through a direct sales force.
Coherent's products are sold internationally through direct sales personnel
located in the United Kingdom, Sweden, Germany, France, Belgium, The
Netherlands, Japan (Lambda Physik for commercial products only),  The Peoples
Republic of China and Hong Kong, as well as through independent representatives
in other parts of the world.  The Company's foreign sales are made principally
to customers in Europe, Japan and Asia Pacific, but sales are also made to
customers in Canada, Mexico, Latin America, Australia, the Middle East and
Africa.  Sales made to independent representatives and distributors are
generally priced in U.S. dollars.  Foreign sales made directly by the Company
are generally priced in local currencies and are therefore subject to currency
exchange fluctuations.   Foreign sales are also subject to other normal risks
of foreign operations, such as protective tariffs and export/import controls.
Coherent's products are broadly distributed and no one customer accounted for
more than 10%  of total sales during fiscal 1997.

     Coherent commenced  direct sales and service for its Medical and Electro-
Optical business segments in Japan effective February 1996 and April 1997,
respectively.  Japan is the largest international market for both business
segments, and creating closer relationships with the Japanese customers enables
the Company to provide stronger support.  Furthermore, the Company can develop
products more rapidly for the Japanese market.

     The Company gives various warranties on its products and offers service on
a contractual basis after the initial product warranty has expired.

                                11

<PAGE>

     Coherent maintains a customer support and field service staff in major
markets in the United States, Mexico, Europe, Japan and Asia Pacific.  This
organization works closely with customers and customer groups in servicing
equipment, training customers to use the Company's products and exploring
additional applications of the Company's technologies.

PRODUCTION AND SOURCES AND AVAILABILITY OF MATERIALS

     The Company's production operations consist primarily of assembling and
testing its products, although the Company manufactures substantially all of
its own laser tubes, optics and diode wafers.  The Company depends upon outside
suppliers for most product components, many of which are manufactured to the
Company's specifications.  The Company has not experienced any significant
difficulty in obtaining raw materials or components in the past.  There is
always a possibility of periodic, short-term disruption in supplies of
critical, high technology components; however, the Company does not believe
that such disruptions would have a material adverse impact on its financial
position or results of operations.

PATENTS AND LICENSES

     Coherent has a significant number of U.S. and foreign technology patents
incorporated into its products.   The Company believes it owns, or has the
right to use, the basic patents covering its products.  However, each year
there are hundreds of patents granted worldwide related to lasers and their
applications and, from time to time, the Company has been notified that it may
be infringing upon patents owned by others.  In the past, the Company has been
able to obtain patent licenses for patents related to its products on
commercially reasonable terms.  The failure to obtain a key patent license from
a third party could cause the Company to incur liabilities for patent
infringement and, in the extreme case, to discontinue the manufacturing of
products that infringe upon the patent.  Management believes that none of the
Company's current products infringe upon a valid claim of any patents owned by
third parties, where the failure to license the patent would have a material
and adverse effect on the Company's financial position or results of
operations.

BACKLOG

     At September 27, 1997, the Company's backlog of orders scheduled for
shipment was approximately $75,429,000, compared with $59,974,000 at September
28, 1996.  Orders used to compute backlog are generally cancelable without
substantial penalties. Historically, the rate of cancellation experienced by
the Company has not been significant; however, since orders are cancelable, the
backlog of orders, at any one time, is not necessarily indicative of future
revenues. The Company anticipates filling the present backlog during fiscal
1998.  Backlog at September 27, 1997, was higher than at September 28, 1996, in
the Electro-Optical business segment and lower in the Medical business segment.
Higher backlog in the Electro-Optical business  is driven by the commercial and
OEM side, as this business has grown faster than the Scientific business and
traditionally has higher backlog due to the nature of the booking process for
OEMs.  This increase was partially offset by the decrease in Medical backlog,
because  manufacturing bottlenecks relating to certain aesthetic products which
existed at the prior fiscal year end, were resolved in the current fiscal year.
Therefore, Medical segment backlog dropped to a more manageable level, as
customers realized faster delivery on their orders.

COMPETITION

     Coherent is the largest laser company in both of its business segments.
No competitor offers the wide range of products that are manufactured and sold
by Coherent.  However, competition is intense in both business segments because
there are a number of small laser companies selling products which compete
directly with one or more Coherent products.

     The markets in which Coherent is engaged are subject to keen competition
and rapid technological change. The principal factors of competition for all
products are reliability, price, 

                                12

<PAGE>

performance, service, marketing and distribution, technological achievement 
and human resources.  Coherent believes that it competes favorably in these 
areas, but continued emphasis upon development of new and improved products, 
and the continued development of successful channels of distribution will be 
necessary to maintain or increase the Company's share of the laser markets in 
which it competes.

RESEARCH AND DEVELOPMENT

     Coherent maintains separate research and development staffs in both of its
major business segments.  Development of new and improved electro-optical and
medical products is primarily the responsibility of engineering department and
applications staffs located in the U.S., Germany and the United Kingdom.  Such
engineering staffs design and develop both new products and enhancements to
existing products.  Coherent works closely with customers, both individually
and through Company sponsored seminars, to develop products to meet customer
application and performance needs.

     The Company operates in an industry which is subject to rapid
technological change.   Its ability to compete and operate successfully depends
upon, among other things, its ability to react to such change.  Accordingly,
Coherent is committed to the development of new products as well as the
improvement and refinement of existing products.  Fiscal 1997 expenditures for
research and development were $39,406,000, 10% of sales, compared to
$37,705,000, 10% of sales, and $31,042,000, 11% of sales, during fiscal 1996
and 1995, respectively.

IMPACT OF ENVIRONMENTAL REGULATION

     The Company believes that compliance with federal, state and local
environmental protection regulations will not have a material adverse effect on
the capital expenditures, earnings, competitive and financial position of the
Company.  The Company is a respondent under Remedial Action Orders issued by
the California Department of Toxic Substance Control relating to an
investigation and remediation of soil and groundwater contamination at its
former facility in the Stanford Industrial Park, Palo Alto, California.  See
Note 11,  "Commitments  and Contingencies",  of the Notes to Consolidated
Financial Statements.

IMPACT OF MEDICAL DEVICE REGULATIONS

     The Company's medical products are subject to regulation and control by
the Center for Devices and Radiological Health, a branch of the Food and Drug
Administration (FDA) within the Department of Health and Human Services.  The
FDA medical device regulations require either an Investigational Device
Exemption (IDE), Pre-Market Approval (PMA) or 510(K) clearance before new
products can be marketed to, or utilized by, the physician.  The Company's
medical products are subject to similar regulations in its major international
markets.  Complying with these regulations is necessary for the Company's
strategy of expanding the markets for and sales of its products into these
countries.

     These approvals may include clinical testing, limitations on the number of
sales, controls of end user purchase price and the extent of product
commercialization.  In certain instances, these constraints can delay planned
shipment schedules as design and engineering modifications are made in response
to regulatory concerns and requests.  The Company's competitors in the medical
field are subject to the same regulations.

     The Company believes that its long established working relationship with
the medical community and the high quality of its products allow it to work
effectively within these regulatory constraints.

                                13

<PAGE>

EMPLOYEES

     At September 27, 1997, Coherent employed 2,131 persons.  The Company's
continued success will depend in large measure on its ability to attract and
retain highly skilled employees, who are in great demand.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
         FINANCIAL CONDITION


YEAR 2000 COMPLIANCE

     The Company is aware of the issues associated with the programming code in
existing computer systems as the millennium (year 2000) approaches.  The "year
2000" problem is pervasive and complex, as virtually every computer operation
will be affected in the same way by the rollover of the two digit year value to
00.  The issue is whether computer systems will properly recognize date
sensitive information when the year changes to 2000.  Systems that do not
properly recognize such information could generate erroneous  data or cause a
system to fail.

     The Company is utilizing both internal and external resources to identify,
correct or reprogram, and test the systems for the year 2000 compliance.  It is
anticipated that all reprogramming efforts will be complete by December 31,
1998, allowing adequate time for testing.  This process includes getting
confirmations from the Company's primary vendors that plans are being developed
or are already in place to address processing of transactions in the year 2000.
However, there can be no assurance that the systems of other companies on which
the Company's systems rely also will be timely converted or that any such
failure to convert by another company would not have an adverse effect on the
Company's systems. Management is in the process of completing its assessment of
the year 2000 compliance costs however, based on information to date (excluding
the possible impact of vendor systems) management does not believe that it will
have a material effect on the Company's earnings.

ASIA-PACIFIC RISK

     Recent economic trends, particularly in the Asia-Pacific marketplace, have
caused a heightened awareness of the impact this portion of the world's economy
can have on the overall economy.  As the Asia-Pacific market currently
represents almost one-third of the worlds buying power and approximately 25% of
Coherent's sales are to this region, changes in this area's economic growth
rate may impact suppliers of product into that market.  While the actual
magnitude of the business at risk is unknown, it is likely that capital
spending in this market will decrease and thus, Coherent's ability to grow
sales in this region may be negatively impacted.


RESULTS OF OPERATIONS

     FOREIGN CURRENCY IMPACT

     With more than half of the Company's revenues outside the United States,
sales and orders were negatively impacted due to the continued strengthening of
the U.S. dollar against other major currencies.  If exchange rates had remained
at last year's levels, sales and orders would have grown 11% and 18%,
respectively, compared to the same twelve months a year ago, instead of the 7%
and 14% increases actually recorded.  At current exchange rates, we anticipate
quarter to quarter comparisons will continue to be negatively effected by
currency adjustments through the first two quarters of fiscal 1998.

     EFFECTS OF HEDGING

     The Company enters into forward exchange contracts to minimize the short-
term impact of foreign currency fluctuations on assets and liabilities and firm
commitments denominated in currencies other than the functional currency of the
reporting entity.  All foreign exchange forward contracts are designated as and
effective as a hedge and are highly inversely correlated to the hedged item as
required by generally accepted accounting principles.  Gains and losses on the
contracts that hedge foreign currency assets and liabilities are included in
other income and offset foreign exchange gains or losses from the revaluation
of intercompany balances or other current assets and liabilities denominated in

                                        17

<PAGE>

currencies other than the functional currency of the reporting entity.  The
cash flow impact of the Company's derivative hedges offsets the cash flow
impact of the foreign  exchange movements on the underlying exposed asset and
liability commitments. Gains and losses on contracts that hedge firm
commitments of foreign currency purchases or sales are deferred and recognized
at the time the hedged transaction is recorded as an offset to the amount  of
the related purchase or sale.  Fair values of exchange contracts are determined
by obtaining quoted market prices of comparable contracts, adjusted through
interpolation where necessary for maturity differences.

     CONSOLIDATED SUMMARY

     During fiscal 1997, proforma net income (excluding the first quarter $9.0
million  after-tax write-off of purchased in-process technology) increased to
$35.3 million ($3.01 per share) compared to net income of $30.3 million ($2.63
per share) for fiscal 1996 and $19.3  million ($1.75 per share) for fiscal
1995. Proforma income before income taxes, excluding the aforementioned write-
off, increased $6.8 million (14%) to $56.1 million for fiscal 1997 compared to
income before income taxes of $49.3 million for fiscal 1996 and $31.8 million
for fiscal 1995.  These increases resulted primarily from higher sales volumes,
gross profits as a percentage of sales, and other income.  The Company's
proforma effective tax rate was 37% (excluding the aforementioned write-off)
and was 39% for both fiscal 1996 and 1995. Actual net income, income before 
income taxes and the effective tax rate for fiscal 1997 were $26.3 million, 
$46.8 million and 44%, respectively.

1997 COMPARED TO 1996

     NET SALES AND GROSS PROFIT

     CONSOLIDATED

     During fiscal 1997, net sales increased $26.6 million (7%) to $391.0
million from $364.4 million in the prior fiscal year, primarily as a result of
increased sales volumes.  The higher sales volumes were primarily in the
Electro-Optical segment (OEMs and commercial customers) and in the Medical
segment (lasers for ophthalmic procedures).  International sales grew at a
higher rate than domestic sales for a total increase of $21.1 million (11%).
Accordingly, international sales were 55% of net sales for the current fiscal
year compared to 53% last year,  reflecting the Company's commitment to grow
its international business.

     The gross profit rate improved to 53% for the current fiscal year compared
to 51% for fiscal 1996.  The improvement in the overall margin resulted
primarily from the higher sales volumes,  higher volumes of higher margin
products and manufacturing efficiencies.

     ELECTRO-OPTICAL

     Electro-Optical net sales increased $19.5 million (10%) in the current
fiscal year to $221.1 million from $201.6 million in the prior fiscal year.
Domestic sales increased $16.0 million (20%) and international sales increased
$3.5  million (3%) in the current fiscal year.  The increase in sales
worldwide,  resulted primarily from higher sales volumes to OEM's and
commercial customers, due to broader acceptance of new products introduced
within the past two years.

     The gross profit rate decreased to 51% from 52% in the prior fiscal year.
The decrease from the prior year resulted primarily from inefficiencies
associated with the start-up phase of the Company's Semiconductor group based
in Santa Clara, California.

     MEDICAL

     Medical net sales increased $7.1 million (4%) to $170.0 million in fiscal
1997 from $162.8 million in fiscal 1996.  International sales increased $17.6
million (25%) while domestic sales decreased $10.5 million (11%) in the current
fiscal year.  The growth was primarily attributable to higher sales volumes in
the ophthalmic business unit.

                                        18

<PAGE>

     The gross profit rate increased to 55% from 51% in the prior fiscal year
primarily due to the higher sales volumes which also are comprised of higher
margin products, such as the VersaPulse for cosmetic procedures, as well as a
higher level of sales through direct sales channels including Japan, China and
Scandinavia.

</TABLE>

     Total operating expenses increased $20.7 million (15%) from the prior
fiscal year.  Exclusive of the first quarter write-off of purchased in-process
technology, operating expenses increased $11.4 million (8%), but as a
percentage of sales remained constant at 39%.

     Current year research and development (R&D) expenses increased $1.7 
million (5%) from the prior year and remained flat at 10% of sales.  The 
absolute dollar increase was primarily in the Company's Electro-Optical 
business segment due to more headcount and related expenses associated with 
the Company's continued emphasis on product development and its recent 
strategic acquisitions.

     Selling, general and administrative (SG&A) expenses increased $9.7 million
(9%) but remained at 29% of sales compared to the prior fiscal year.  Sales,
marketing and service expenses increased $7.6  million (10%) and as a
percentage of sales increased to 21% from 20% in fiscal 1996.  This expense was
driven by an increase in headcount to support the growing business, the change
to direct sales in Japan, China and Scandinavia, as well as an increase in the
level of workshops and trade shows worldwide.  Administration expenses
increased $2.1 million (7%) but as a percentage of sales remained at 9%.  This
increase was driven by costs related to recent strategic acquisitions, facility
expansions, and selling in direct channels in Japan, China and Scandinavia.

     OTHER INCOME (EXPENSE)

     Other income, net, decreased $0.1 million during the current year compared
to the corresponding prior year period.  The current year's other income
included a $3.5 million gain on the Company's sale of its former facility while
the previous fiscal year's other income included a $1.6 million gain on sale of
the Company's holdings in another medical laser company.  The remaining
fluctuation of $1.8 million  was due to lower interest income on lower average
cash and investment balances, higher interest expense due to the fiscal 1996
capitalization of interest ($0.7 million) on the refurbishing of the former
facility (sold in fiscal 1997), higher foreign exchange losses due to the
strengthening of the U.S. dollar against the major foreign currencies, and
higher minority interest income from the improved performance in the Lambda
Physik Group.

     INCOME TAXES

     The Company's effective tax rate for the current year was 44%.  The 
Company's proforma effective tax rate for the fiscal year (excluding the $9.3 
million pre-tax write-off of purchased in-process technology) was 37%, 
compared to 39% for the same period last year.  The Company's proforma 
effective tax rate decreased as a result of increases in foreign tax credit 
utilization, foreign sales corporation benefit and changes in the 
distribution of taxable income  by taxing  jurisdiction.

1996 COMPARED TO 1995

     NET SALES AND GROSS PROFIT

     CONSOLIDATED

     During fiscal 1996, net sales increased $78.9 million (28%) to $364.4
million from $285.5 million, resulting primarily from increased sales volumes.
Such higher volumes occurred primarily with OEM's and commercial customers in
the Electro-Optical segment and with lasers for aesthetic surgery in the
Medical segment.  International sales grew at a higher rate than domestic sales
in both segments for a total increase of $45.2 million (31%).  Accordingly,
international sales were 53% of net sales for fiscal 1996 year compared to 51%
for fiscal 1995,  reflecting the Company's commitment to grow its international
business.

     The gross profit rate improved to 51% for fiscal 1996 compared to 50% for
fiscal 1995.  The improvement in the overall margin resulted primarily from
higher sales volumes of high margin products and manufacturing efficiencies.

     ELECTRO-OPTICAL

     Electro-Optical net sales increased $42.3 million (27%) in fiscal 1996 to
$201.6 million from $159.3 million in fiscal 1995.  International sales
increased $26.6 million (28%) and domestic sales increased $15.7 million (24%)
in fiscal 1996 compared to fiscal 1995.  The increased sales,  both
internationally and domestically, resulted primarily from higher sales volumes
to OEM's and commercial customers, due to broader acceptance of new products
introduced within the past two years and due in part to increased sales
associated with business acquisitions.

     The gross profit rate increased to 52% in fiscal 1996 from 50% in fiscal
1995.  The increase over the prior year resulted from efficiencies gained from
the higher sales volumes and a more favorable product mix.

     MEDICAL

     Medical net sales increased $36.6 million (29%) to $162.8 million in
fiscal 1996 from $126.2 million in fiscal 1995.  International sales increased
$18.7 million (36%) while domestic sales increased $18.0 million (24%) in
fiscal 1996.  The growth was primarily attributable to higher sales volumes of
the Ultrapulse for cosmetic applications.

     The gross profit rate increased to 51% in fiscal 1996 from 50% in fiscal
1995 primarily due to the higher sales volumes which also are comprised of
higher margin products, such as the Ultrapulse for cosmetic procedures.

<PAGE>

     Total operating expenses increased $29.9 million (27%) from fiscal 1995
but as a percentage of sales remained constant at 39%.

     Fiscal 1996 research and development (R&D) expenses increased $6.7 million
(21%) from the prior year but decreased as a percentage of sales from 11% to
10%.  The absolute dollar increase was most significant in the Company's
Electro-Optical business segment due to more headcount and related expenses
associated with the Company's continued emphasis on product development and its
recent strategic acquisitions.  The Company intends to build upon its
leadership position and continue this strong commitment to product development.
For example, two new models of our UltraPulse-Registered Trademark- medical
laser system allow physicians from all size practices to participate in the
growing market for skin resurfacing with the laser that is recognized as the
"gold standard" for this application.  The Company's new diode-pumped solid-
state (DPSS) laser, used to improve the performance of computer hard-disk
drives, provides hard-disk media manufacturers a laser capable of handling high-
volume production while maintaining the highly stable operations required for
this application.  At the American Academy of Ophthalmology in Chicago in the
fall of 1996, the Company introduced the Selecta 7000-TM-.  Based on initial
results using this system for Selective Laser Trabeculoplasty (SLT), the
Company believes that the Selecta 7000 has the potential for becoming the
standard treatment for treating primary open-angle glaucoma.

     Selling, general and administrative (SG&A) expenses increased $23.3
million (29%) during fiscal 1996 but remained at 29% of sales compared to the
prior fiscal year.  Sales, marketing and service expenses increased $17.7
million (32%) and as a percentage of sales increased to 20% from 19% in fiscal
1995.  This expense was driven by an increase in headcount to support the
growing business, the Medical segment's change to direct sales in Japan, and an
increase in the level of workshops and trade shows worldwide.  Administration
expenses increased $5.6 million (21%) but as a percentage of sales remained at
9%.  This increase was driven by costs related to recent strategic
acquisitions, facility expansions, and bonuses associated with improved
operating performance over the prior year.


     OTHER INCOME (EXPENSE)

     Total other income, net increased by $2.7 million during fiscal 1996.
This increase resulted primarily from a $1.6 million gain from the third
quarter sale of the Company's holdings in another medical laser company, and
$1.2 million higher interest and dividend income, net, due to capitalization of
interest associated with the refurbishment of the Porter facility ($0.7
million) and the construction of the Auburn Building III ($0.1 million).  The
funds generated by operations and the sales of shares under the employee stock
option and purchase plans helped fund the acquisition of such facilities
without increasing average borrowings nor significantly reducing average cash
and short-term investments. The Porter Drive facility was completed in
September, 1996 and was sold in fiscal 1997.

     INCOME TAXES

     The Company's effective tax rate  for fiscal 1996 and fiscal 1995 remained
constant at 39%.


FINANCIAL CONDITION

LIQUIDITY AND CAPITAL RESOURCES

     The Company's primary sources of liquidity are cash and short-term
investments of $31.6 million at September 27, 1997.  Additional sources of
liquidity are the Company's multi-currency line of credit and bank credit
facilities totaling $54.3 million as of September 27, 1997, of which $35.8
million is unused and available under these credit facilities.  During fiscal
1997, such facilities have been used in Europe and Japan.  Because of the
Company's low debt to equity ratio (0.14:1), management believes that
additional cash could be borrowed if necessary; however, cash flow from
operations, cash and 

                                    21

equivalents, short-term investments and available lines of credit are 
expected to be sufficient to fund operations for fiscal 1998.  The Company 
has certain financial covenants related to its lines of credit.  At September 
27, 1997, the Company is in compliance with these covenants (see Note 5, 
"Short-term Borrowings", of the Notes to Consolidated Financial Statements").

CHANGES IN FINANCIAL CONDITION

     Cash and equivalents at September 27, 1997 increased by $12.2 million 
(133%) from September 28, 1996.  Operations and changes in exchange rates 
generated $31.2 million including a decrease in short-term investments of 
$15.2 million.  Investing activities used $32.3 million; $24.3 million was 
used to acquire property and equipment (net of proceeds from disposition of 
property and equipment), $15.4 million was used for business acquisitions 
partially offset by $9.6 million provided from the sale of the Porter Drive 
facility.  Financing activities provided $13.3 million, sales of shares under 
employee benefit plans and collection of notes receivable from stock sales 
generated $5.5 million, increased net borrowings provided $15.7 million and 
the reduction of cash overdrafts used $7.9 million.

To the Stockholders and Board of Directors of Coherent, Inc.:

     We have audited the accompanying consolidated financial statements of
Coherent, Inc. and its subsidiaries, listed in Item 14.(a)1.  Our audits also
included the consolidated financial statement schedule listed in Item 14.(a)2.
These financial statements and the financial statement schedule are the
responsibility of the Company's management.  Our responsibility is to express
an opinion on the financial statements  and the financial statement schedule
based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Coherent, Inc. and its
subsidiaries at September 27, 1997 and September 28, 1996, and the results of
their operations and their cash flows for each of the three years in the period
ended September 27, 1997 in conformity with generally accepted accounting
principles.  Also, in our opinion, such financial statement schedule, when
considered in relation to the basic consolidated financial statements taken as
a whole, presents fairly in all material respects the information set forth
therein.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.   SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of Coherent, 
Inc. and its majority owned subsidiaries (collectively, the Company).  All 
significant intercompany balances and transactions have been eliminated. 
Investments in business entities in which the Company does not have control, 
but has the ability to exercise significant influence over operating and 
financial policies (generally 20-50% ownership), are accounted for by the 
equity method.

FISCAL YEAR

     The Company's fiscal year ends on the Saturday  nearest to September 30. 
Consequently, the Company's fiscal years  1997, 1996 and 1995 included 52 
weeks.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally 
accepted accounting principles requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities and 
disclosure of contingent assets and liabilities at the date of the financial 
statements and the reported amounts of revenues and expenses during the 
reporting period.  Such estimates include, but are not limited to, allowances 
for uncollectible accounts receivable and sales returns reserves, inventory 
reserves, warranty costs, depreciation and amortization, taxes and 
contingencies.  Actual results could differ from those estimates.

FOREIGN CURRENCY TRANSLATION

     The functional currency of the Company's foreign subsidiaries is their 
respective local currencies.  Accordingly, gains and losses from the 
translation of the financial statements of the foreign subsidiaries are 
reported as a separate component of stockholder's equity.

CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

     The Company's policy is to invest in various short-term debt instruments 
including certificates of deposit, bankers acceptances and repurchase 
agreements of major banks and institutions, obligations of the U.S. Treasury 
and U.S. Government agencies, tax-exempt municipal securities and commercial 
paper with credit ratings of A1 and P1.  All highly liquid debt instruments 
purchased with a remaining maturity of three months or less are classified as 
cash equivalents.

INVENTORIES

     Inventories are stated at the lower of cost (first-in, first-out) or 
market. Inventories are as follows:

                                                   1997           1996
- -----------------------------------------------------------------------------
                                                     (In thousands)
Purchased parts and assemblies                    $25,756        $18,446
Work-in-process                                    28,917         24,244
Finished goods                                     31,773         23,145
- -----------------------------------------------------------------------------
Inventories                                       $86,446        $65,835
- -----------------------------------------------------------------------------
- -----------------------------------------------------------------------------

                                  36
<PAGE>
PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost and are generally depreciated 
or amortized using the straight-line method.  Cost and estimated useful lives 
are as follows:

                                       1997      1996         Useful Life
- -----------------------------------------------------------------------------
                                          (In thousands)
Land                               $  7,404    $  5,833
Buildings and improvements           34,912      43,317       20-31 years
Equipment, furniture and fixtures    75,392      63,723        3-10 years
Leasehold improvements               10,824       4,196      Terms of lease
- -----------------------------------------------------------------------------
Property and equipment             $128,532    $117,069
- -----------------------------------------------------------------------------
- -----------------------------------------------------------------------------

     Included in buildings and improvements is capitalized interest on 
construction-in-progress of $121,000 at September 27, 1997 (accumulated 
amortization of $1,600) and $824,000 at September 28, 1996 (no accumulated 
amortization).

GOODWILL

     Goodwill relates to acquired subsidiaries and is being amortized on a 
straight-line basis over estimated useful lives of three to forty years.  The 
Company evaluates its long-lived assets for impairment whenever events or 
changes in circumstances indicate that the carrying value of an asset may not 
be recoverable.

WARRANTY

     The Company warrants certain of its products and provides for estimated 
product warranty costs at the time of sale.

REVENUE RECOGNITION

     The Company generally recognizes revenue from product sales upon 
shipment or title transfer, if later, and from service upon performance or 
over the terms of the service contract as appropriate.

CONCENTRATION OF CREDIT RISK

     Financial instruments which may potentially subject the Company to 
concentrations of credit risk consist principally of cash equivalents, 
short-term investments and accounts receivable.  The Company places its 
investments only in U.S. Treasury obligations or with high credit quality 
financial institutions and, by policy, limits the amount of credit exposure 
to any one institution.  The majority of its short-term investments are in 
certificates of deposit and notes at September 27, 1997.  The majority of the 
Company's accounts receivable are derived from sales to customers for medical 
and surgical applications, scientific research applications, and OEM's.  The 
Company performs ongoing credit evaluations of its customers' financial 
condition and limits the amount of credit extended when deemed necessary but 
generally requires no collateral.  The Company maintains reserves for 
potential credit losses.

INCOME TAXES

     Federal income taxes have not been provided on a portion of the unremitted
earnings of foreign subsidiaries either because such earnings are intended to
be permanently reinvested or because foreign tax credits are available to
offset any planned distributions of such earnings.  The total amount of
unremitted earnings of foreign subsidiaries was approximately $17,184,000 at
September 27, 1997.


                                  37
<PAGE>

Withholding taxes of approximately $597,000 would be payable upon 
repatriation of such earnings which would result in additional foreign tax 
credits.

DERIVATIVES

     The Company enters into forward exchange contracts to minimize the 
short-term impact of foreign currency fluctuations on assets and liabilities 
and firm commitments denominated in currencies other than the functional 
currency of the reporting entity.  All foreign exchange forward contracts are 
designated as and effective as a hedge and are highly inversely correlated to 
the hedged item as required by generally accepted accounting principles.  
Gains and losses on the contracts that hedge foreign currency assets and 
liabilities are included in other income and offset foreign exchange gains or 
losses from the revaluation of intercompany balances or other current assets 
and liabilities denominated in currencies other than the functional currency 
of the reporting entity. The cash flow impact of the Company's derivative 
hedges offsets the cash flow impact of the foreign  exchange movements on the 
underlying exposed asset and liability commitments. Gains and losses on 
contracts that hedge firm commitments of foreign currency purchases or sales 
are deferred and recognized at the time the hedged transaction is recorded as 
an offset to the amount  of the related purchase or sale.  Fair values of 
exchange contracts are determined by obtaining quoted market prices of 
comparable contracts, adjusted through interpolation where necessary for 
maturity differences.

COMMON AND EQUIVALENT PER SHARE DATA

     Common and equivalent per share data is based upon the weighted average 
number of common shares outstanding during the period plus dilutive common 
share equivalents and shares issuable under the Productivity Incentive Plan. 
Dilutive common share equivalents include outstanding stock options when the 
exercise price is less than the average market price and shares subscribed 
under the Employee Stock Purchase Plan.  The number of common and dilutive 
common equivalent shares used were 11,740,000 in 1997, 11,544,000 in 1996, 
and 11,062,000 in 1995.

STOCK-BASED COMPENSATION

     As permitted under the Statement of Financial Accounting Standards No. 
123 (SFAS 123), "Accounting for Stock-Based Compensation" the Company 
accounts for stock-based awards to employees using the intrinsic value method 
in accordance with Accounting Principles Bulletin No. 25 (APB 25), 
"Accounting for Stock Issued to Employees".   See Note 9.

RECLASSIFICATIONS

     Certain prior year amounts have been reclassified to conform with the 
current year presentation.  Such reclassifications had no impact on net 
income or retained earnings for any year presented.

2.   ACQUISITIONS

     During the three fiscal years ended September 27, 1997, the Company made 
the acquisitions  described in the following paragraphs, each of which has 
been accounted for as a purchase.  The consolidated financial statements 
include the operating results of each business from the date of acquisition. 
Proforma results of operations have not been presented, because the effects 
of these acquisitions were not material on either an individual or an 
aggregate basis. The amounts allocated to purchase in-process technology were 
determined through established valuation techniques in the high technology 
industry  and were expensed upon acquisition, because technological 
feasibility had not been established and no future alternative uses existed.  
Research and development costs to bring the products from the acquired 
companies to technological feasibility are not expected to have a material 
impact on the Company's future results of operations or cash flows.  Amounts 
allocated to goodwill and other intangibles are amortized on a straight line 
basis over periods ranging from five to ten years.

                                  38
<PAGE>

     In May 1997, Coherent acquired the assets and operations of Ealing 
Electro-Optics, located in Watford, England and its U.S. subsidiary located 
in Holliston, Massachusetts for approximately $9.5 million in cash.  Ealing 
is a recognized leader in the design and manufacture of precision optical 
assemblies as well as complete lens and thermal imaging test systems.  In 
addition, Ealing is a distributor of electro-optic components and its "Gold" 
catalog sells over 5,000 components to the photonics industry. The 
acquisition was accounted for as a purchase and, accordingly, the Company has 
recorded the approximately $4.0 million excess of the purchase price over the 
fair value of net assets acquired as goodwill, which is being amortized over 
10 years.

     In December 1996, Coherent acquired 80% of the outstanding shares of 
Tutcore OY Ltd., located in Tampere, Finland for approximately $10.0 million 
(consisting of $4.0 million of cash, $5.4 million of deferred payment 
obligations and $0.6 million of acquisition costs).  Tutcore specializes in 
the growth and processing of aluminum-free epitaxial wafers used in 
semiconductor lasers.   Also in December 1996, Coherent purchased the net 
assets of Micracor, Inc. of Acton, Massachusetts for approximately $0.9 
million (consisting of $0.8 million of cash and $0.1 million of acquisition 
costs).  Micracor manufactures materials used in semiconductor-based solid 
state microchip lasers for the telecommunications market. These acquisitions 
were accounted for as purchases and, accordingly, the acquired assets and 
liabilities were recorded at their estimated fair market values at the dates 
of the acquisitions.  The aggregate purchase price of $10.9 million 
(including acquisition costs) has been allocated to the assets and 
liabilities acquired.  Approximately $9.3 million of the total purchase price 
for these entities represented the value of in-process technology that had 
not yet reached technological feasibility and had no alternative future use, 
and was charged to operations during the first quarter of fiscal 1997.  
Coherent's consolidated results of operations include the operating results 
of the acquired companies from their acquisition dates.

     During the second quarter of fiscal 1996, the Company reached agreement 
with Matsumoto Medical Instruments, its former distributor of medical 
products in Japan, to acquire exclusive distribution rights for Coherent's 
products in Japan, effective immediately.  The agreement also provided for 
Coherent to repurchase its inventory from Matsumoto and allows for Coherent 
to assume full service and warranty support to its customers on an exclusive 
basis immediately.  The $5,048,000 excess of the purchase price over the net 
tangible assets acquired has been allocated to the exclusive sales rights and 
related regulatory approvals.  This amount is being amortized over a five 
year period having commenced during the third quarter of fiscal 1996.

     In the first quarter of fiscal 1996, the Company acquired certain net 
assets of Applied Laser Systems (ALS) and the Laser Optics Division of ATx 
Telecom Systems, Inc. (a subsidiary of Amoco Technology Company) for $2.5 
million.  ALS is a pioneer in the design and manufacture of low power diode 
laser modules.  ATx is the developer of unique coating processes for optical 
components including lenses and mirrors used in the fabrication of solid 
state lasers and other products.  These technologies complement Coherent's 
existing laser instrumentation, precision optics and laser diode product 
lines sold to OEMs and end users.  The Company recorded $1.2 million of 
goodwill associated with the purchases which is being amortized over five 
years.

     Effective June 30, 1995, the Company acquired the business and net 
assets of Adlas GmbH and Co.  KG (Adlas), located in Lubeck, Germany for 
approximately $7.4 million.  The Company paid $1.9 million in cash and 
recorded a $3.5 million note payable (paid in December 31, 1995) and a $2.0 
million deferred payment due December 31, 1997.  These payments do not accrue 
interest and are contingent on achieving certain net sales goals.  The 
Company recorded the payments when it determined the net sales goals were 
probable of being attained.  The acquisition has been accounted for as a 
purchase and, accordingly, the Company has recorded the $7.2  million excess 
of the purchase price over the fair value of net tangible assets acquired as  
goodwill which is being amortized over ten years.  Adlas is a leading 
manufacturer of DPSS lasers used in commercial applications such as 
semiconductor inspection, reprographics, materials processing, and analytical 
instrumentation.

     Effective March 24, 1995, Coherent and ATx Telecom Systems, Inc. (AMOCO)
entered into an "Asset Purchase and Sale Agreement" whereby Coherent purchased
certain assets (consisting primarily

                                  39
<PAGE>

of patents and technology licenses) relating to Amoco's diode pumped 
solid-state laser technology for $4.5 million in cash.  The intangible assets 
acquired of $4.3 million are being amortized primarily over a ten year period.

4.   FINANCIAL INSTRUMENTS

FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following methods and assumptions were used to estimate the fair 
value of each class of financial instruments for which it is practicable to 
estimate that value.

     Cash equivalents and short-term investments are stated at fair market 
value based on quoted market prices.

                                  40
<PAGE>

     The recorded carrying amount of the Company's long-term obligations 
approximates fair market value.

     The carrying amount and fair value of foreign exchange contracts was 
$27.8 million at September 27, 1997. The carrying amount and fair value of 
foreign exchange contracts were $19.1 million and $18.9 million, respectively 
at September 28, 1996.  The fair value of foreign exchange contracts is 
estimated by obtaining quoted market prices of comparable contracts, adjusted 
through interpolation where necessary for maturity differences.

FOREIGN EXCHANGE CONTRACTS

     In the normal course of business, the Company has exposures to foreign 
currency fluctuations arising from foreign currency sales and purchases and 
intercompany transactions, among other things.  The Company uses foreign 
exchange forward contracts to limit its exposure to foreign exchange losses 
arising from nonfunctional currency payables and receivables and firm 
commitments.  The Company evaluates its net exposure therefrom and enters 
into forward contracts to hedge the net exposure over a specified amount.  
These contracts are executed with credit-worthy financial institutions  and 
are denominated in currencies of major industrial nations.   Gains and losses 
on these contracts serve as hedges in that they offset fluctuations that 
would otherwise impact the Company's financial results.  Costs associated 
with entering into such contracts are generally amortized over the life of 
the instruments and are not material to the Company's financial results.

     At September 27, 1997 and September 28, 1996, the Company had foreign 
currency forward contracts outstanding to hedge foreign currency accounts 
receivable and accounts payable and sales backlog usually shippable within 90 
days.  These contracts have maturities which typically range from 90 to 180 
days and are intended to reduce exposure to foreign currency exchange risk. 
The aggregate fair value and unrealized gain (loss) of foreign exchange 
contracts is as follows:

million at 8% for the mortgage on the  CEEL  facility, $2.2 million at 1.5% 
to 8% of outside financing for Tutcore,  $0.4 million at 2% of outside 
financing by Lambda Japan and $0.2 million for the financing of equipment 
with varying interest rates from 7.8% to 8.1%.  Notes payable are generally 
secured by the related assets financed.

                                  43
<PAGE>

     BONDS PAYABLE - Bonds payable were issued to finance the construction of 
certain facilities and acquisition of equipment which secure repayment of the 
bonds. The bonds are payable in installments through 2008 with a variable 
interest rate (3.3% at September 27, 1997) not to exceed 12%.  The bonds are 
guaranteed by a letter of credit issued by Union Bank with an annual fee of 
1.5%.

     Annual  maturities  of debt  are: 1998 - $3,629,000, 1999 - $507,000, 
2000 - $1,631,000, 2001 - $879,000, 2002 - $2,979,000 and thereafter 
$3,669,000.

8.   STOCKHOLDERS' EQUITY

     Each outstanding share of the Company's common stock carries a stock 
purchase right (right) issued pursuant to a dividend distribution declared by 
the Company's Board of Directors and distributed to stockholders of record on 
November 17, 1989.  When exercisable, each right entitles the stockholder to 
buy one share of the Company's common stock at an exercise price of $80.  The 
rights will become exercisable following the tenth day after a person or 
group announces acquisition of 20% or more of the Company's common stock or 
announces commencement of a tender offer, the consummation of which would 
result in ownership by the person or group of 30% or more of the common 
stock.  The Company will be entitled to redeem the rights at $.01 per right 
at any time on or before the 10th day following the acquisition by a person 
or group of 20% or more of the Company's common stock.

     If, prior to redemption of the rights, the Company is acquired in a 
merger or other business combination in which the Company is the surviving 
corporation, or a person or group acquires 30% or more of the Company's 
common stock, each right owned by a holder of less than 20% of the common 
stock will entitle its owner to purchase, at the right's then current 
exercise price, a number of shares of common stock of the Company having a 
fair market value equal to twice the right's exercise price.  If the Company 
sells more than 50% of its assets or earning power or is acquired in a merger 
or other business combination in which it is not the surviving corporation, 
the acquiring person must assume the obligations under the rights and the 
rights will become exercisable to acquire common stock of the acquiring 
person at the discounted price.

9.   EMPLOYEE STOCK OPTION AND BENEFIT PLANS

PRODUCTIVITY INCENTIVE PLAN

     The Productivity Incentive Plan (Plan) provides for quarterly 
distributions of common stock and cash to each eligible employee.  The 
amounts of the distributions are based on consolidated pre-tax profit, the 
market price of the Company's common stock and the employee's salary.  The 
fair market value of common stock  and cash that are earned under the Plan 
are charged to expense.  For fiscal 1997, 15,308 shares (fair market value of 
$686,029) and $4,247,005 were accrued for the benefit of employees.  For 
fiscal 1996, 15,447 shares (fair market value of $644,897) and $3,730,871 
were accrued for the benefit of employees. For fiscal 1995, 18,593 shares 
(fair market value of $482,672) and $2,597,904 were accrued for the benefit 
of employees.  At September 27, 1997 the Company had 34,632 shares of its 
common stock reserved for future issuance under the Plan.

COHERENT EMPLOYEE RETIREMENT AND INVESTMENT PLAN

     Under the Coherent Employee Retirement and Investment Plan, the Company 
matches employee contributions to the Plan up to a maximum of 6% of the 
employee's individual earnings.  Employees become eligible for after tax 
participation and for Company matching contributions after completing one 
year of service.  The Company's contributions (net of forfeitures) for fiscal 
1997, 1996, and 1995 were $3,057,000, $2,579,000, and $2,519,000, 
respectively.

                                  44
<PAGE>

SUPPLEMENTAL RETIREMENT PLAN

     The Company has a Supplemental Retirement Plan for senior management 
personnel which permits the participants to contribute up to 24% of their 
before tax earnings to a trust.  The Company will match these contributions 
up to an amount equal to 6% of such participants' earnings less any amounts 
contributed by the Company to such participant under the Coherent Employment 
Retirement and Investment Plan.  The Company's contributions (net of 
forfeitures) for fiscal 1997, 1996, and 1995 were $17,834, $13,510, and 
$12,344, respectively.

EMPLOYEE STOCK PURCHASE PLAN

     The Company has an Employee Stock Purchase Plan whereby eligible 
employees may authorize payroll deductions of up to 10% of their regular base 
salary to purchase shares at the lower of 85% of the fair market value of the 
common stock on the date of commencement of the offering or on the last day 
of the twelve-month offering period.  In fiscal 1997, 77,603 shares were 
purchased by and distributed to employees at an average price of $31.39 per 
share.  In fiscal 1996, 124,400 shares were purchased by and distributed to 
employees at an average price of $16.43 per share.  In fiscal 1995, 150,300 
shares were purchased by and distributed to employees at an average price of 
$11.80 per share.

     At September 27, 1997, $2,625,000 had been contributed by employees that 
will be used to purchase a maximum of 113,045 shares  in fiscal 1998 at a 
price determined under the terms of the Plan.  At September 27, 1997, the 
Company had 431,000 shares of its common stock reserved for future issuance 
under the plan.

STOCK OPTION PLANS

     Coherent, Inc. has two Stock Option Plans and a non-employee Directors' 
Stock Option Plan.  Under these plans, the Company may grant options to 
purchase up to 3,000,000 and 150,000 shares of common stock, respectively. 
Employee options are generally exercisable three years from the grant date, 
which typically coincides with the annual shareholders meeting, however, 
initial grants to employees vest 25% annually. Director options are 
automatically granted to non-employee directors of the Company.  Such 
directors initially receive a stock option for 10,000 shares exercisable over 
a four-year period.  Additionally, the non-employee directors receive an 
annual grant of 2,500 shares exercisable four years from the date of grant. 
Grants under all plans expire six years from the original grant date, and are 
exercisable for the fair market value of the common stock on the date of the 
grant.

Option activity for all plans is summarized as follows:

</TABLE>

     Statement of Financial Accounting Standards No. 123, "Accounting for 
Stock-Based Compensation," (SFAS 123) requires the disclosure of proforma net 
income (loss) and earnings (loss) per share had the Company adopted the fair 
value method as of the beginning of fiscal 1996.  Under SFAS 123, the fair 
value of stock-based awards to employees is calculated through the use of 
option pricing models, even though such models were developed to estimate the 
fair value of freely tradable, fully transferable options without vesting 
restrictions, which significantly differ from the Company's stock option 
awards.  These models also require subjective assumptions, including future 
stock price volatility and expected time to exercise, which greatly affect 
the calculated values.  The Company's calculations were made using the 
Black-Scholes option pricing model with the following weighted average 
assumptions:  expected life 3.85 to 4.07 years; stock volatility 46.7% for 
both years; risk-free interest rates of 6.2% for fiscal 1997 and 5.2% for 
fiscal 1996 and no dividends during the expected term.  The Company's 
calculations are based on a single option valuation approach and forfeitures 
are recognized as they occur.  If the computed fair values of the 1997 and 
1996 awards had been amortized to expense over the vesting period of the 
awards, proforma net income and earnings per share would appear as follows:

                                           1997          1996
                                           ----          ----
Net income               As reported    $26,292        $30,314
                         Proforma       $23,765        $29,032

Net income per share     As reported    $  2.24        $  2.63
                         Proforma       $  2.02        $  2.51

However, the impact of outstanding non-vested stock options granted prior to 
fiscal 1996 has been excluded from the proforma calculation; accordingly, the 
fiscal 1997 and 1996 proforma amounts are not indicative of future period 
proforma amounts, when the calculation will apply to all applicable stock 
options.

NOTES RECEIVABLE FROM STOCK SALES

     Notes receivable from stock sales result from the exercise of stock 
options for notes.  The notes are full recourse promissory notes bearing 
interest at 7.1% and are collateralized by the stock issued upon exercise of 
the stock options.  Interest is payable annually and principal is due through 
1999.

     Rent expense was $7,462,000 in fiscal 1997, $5,305,000 in fiscal 1996, 
and $3,015,000 in fiscal 1995.

     In September 1988, the Company entered into several agreements with 
Patlex Corporation (Patlex) whereby the Company was granted licenses to 
several laser related patents developed by Dr. Gordon Gould and assigned to 
Patlex.  Under the terms of the agreements, the Company pays royalties to 
Patlex of 5% or 3.5% and 2% of certain defined domestic sales and 
international sales, respectively, subject to certain exceptions and 
limitations.  Royalty expense under these agreements was $1,131,000 in fiscal 
1997, $1,324,000 in fiscal 1996, and $1,123,000 in fiscal 1995.  The patents 
expire on various dates through May 2005.

CONTINGENCIES

     Certain claims and lawsuits have been filed or are pending against the 
Company.  In the opinion of management, all such matters have been adequately 
provided for, are without merit, or are of such kind that if disposed of 
unfavorably, would not have a material adverse effect on the Company's 
consolidated financial position or results of operations.

     The Company, along with several other companies, has been named as a 
party to a remedial action order issued by the California Department of Toxic 
Substance Control relating to soil and groundwater contamination at and in 
the vicinity of the Stanford Industrial Park in Palo Alto, California, where 
the Porter Drive facility is located.  The responding parties to the Regional 
Order (including the Company) have completed Remedial Investigation and 
Feasibility Reports, which were approved by the

                                  47
<PAGE>

State of California.  The responding parties have installed four remedial  
systems and have reached agreement with responding parties on final cost 
sharing.

     The Company was also named, along with other parties, to a remedial 
action order for the Porter Drive facility site itself in Stanford Industrial 
Park. The State of California has approved the Remedial Investigation Report, 
Feasibility Study Report, Remedial Action Plan Report and Final Remedial 
Action Report, prepared by the Company for this site.  The Company has been 
operating remedial systems at the site to remove subsurface chemicals since 
April 1992.

     During fiscal 1997, the Company settled with the prior tenant and 
neighboring companies, on allocation of the cost of investigating and 
remediating the site at 3210 Porter Drive and the bordering site at 3300 
Hillview Avenue.

     Management believes that the Company's probable, nondiscounted net 
liability at September 27, 1997 for remaining costs associated with the above 
environmental matters is $0.3 million which has been previously accrued.  
This amount consists of total estimated probable costs of $1.5 million ($0.2 
million included in accrued expenses and $1.3 million included in other 
long-term liabilities) reduced by minimum probable recoveries of $1.2 million 
included in other assets from other parties named to the order.

12.  BUSINESS SEGMENTS

     The Company operates  in two industry segments.  The Company designs, 
manufactures and markets electro-optical products such as lasers, optics and 
related accessories, and medical products such as laser and optical systems 
used for surgical and therapeutic applications.

     Intersegment sales are accounted for primarily at domestic selling 
prices. Intercompany sales between geographic areas are accounted for at a 
discount from domestic selling prices.  Corporate assets are principally 
those not identifiable to a segment and include such items as cash and 
equivalents, short-term investments, certain receivables, prepaid expenses, 
deferred income taxes, certain property and equipment, assets held for sale 
and other assets. Corporate expenses include depreciation of corporate assets 
and general legal expenses.

     Geographically, the Company has sales in the United States, Asia-Pacific 
(including Australia and New Zealand), Europe (primarily in Germany and the 
United Kingdom), and rest  of the world.

14.  RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 1997, the Financial Accounting Standards Board adopted 
Statements of Financial Accounting Standards No. 130 (Reporting Comprehensive 
Income), which requires that an enterprise report, by major components and as 
a single total, the change in its net assets during the period from nonowner 
sources; and No. 131 (Disclosures about Segments of an Enterprise and Related 
Information), which establishes annual and interim reporting standards for an 
enterprise's business segments and related disclosures about its products, 
services, geographic areas, and major customers.  Adoption of these 
statements will not impact the Company's consolidated financial position, 
results of operations or cash flows.  Both statements are effective for 
fiscal years beginning  after December 15, 1997, with earlier application 
permitted.

     In February 1997, the Financial Accounting Standards Board issued SFAS 
No. 128, "Earnings Per Share," which will be adopted by the Company in the 
first quarter of fiscal 1998 as required by the statement.  Upon adoption of 
SFAS No. 128, the Company will present basic earnings per share and diluted 
earnings per share.  Basic earnings per share will be computed based on the 
weighted average number of shares outstanding during the period.  Diluted 
earnings per share will be computed based on the weighted average number of 
shares outstanding during the period increased by the effect of dilutive 
stock options and stock purchase contracts using the treasury stock method.  
Proforma basic earnings per share for fiscal 1997 is $2.32 compared to $2.74 
for fiscal 1996.  Proforma diluted earnings per share for fiscal 1997 is 
$2.24 compared to $2.63 for fiscal 1996.
