Laserati

Santa Clara, Calif., April 22, 2008 – Coherent, Inc. (Santa Clara, CA) (Nasdaq: COHR) has launched the Talisker as the world’s first fiber-based laser to offer high power, picosecond output in a rugged industrial package. With over 18 watts of average power at a pulse repetition rate of 200 kHz (pulsewidth < 15 ps), this first fiber-based laser from Coherent will enable precision micromachining with high throughput and negligible HAZ (heat affected zone) Talisker comes available with a choice of infrared (1064 nm), visible (532 nm) or ultraviolet (355 nm) wavelengths and can be used on virtually any material type, including metals, polymers, glass and semiconductors. Talisker is also configured to facilitate integration and for ease of use. For instance, its internal web server simplifies remote diagnostics and preventative maintenance. Plus, the compact laser head measures only 17 cm x 39 cm x 77 cm.

Talisker is a mode-locked laser with a unique scalable architecture that combines the desirable characteristics of both fiber-based and free space lasers. Specifically, Talisker utilizes a fiber-based oscillator to ensure industrial-grade stability, together with a bulk amplifier which boosts peak powers to greater than 10 megawatts. In contrast, traditional fiber lasers are limited to peak powers that are orders of magnitude lower than this to avoid self-damage.

Talisker is intended for many micromachining applications including microelectronics, biomedical, semiconductor and solar device industries. Specific applications include drilling high quality holes in silicon and metals, direct write of flexible circuits/displays, scribing of flat panel displays/solar cells, micro milling, wafer dicing and metal surface treatments.

Founded in 1966, Coherent, Inc. is a world leader in providing laser-based solutions to the commercial and scientific research markets.

Santa Clara, California – December 18, 2007 – Coherent, Inc. (Nasdaq COHR) announced today that the Securities and Exchange Commission (“SEC”) has denied the Company’s motion to stay decision of The NASDAQ Stock Market LLC (“Nasdaq”), to suspend and delist the Company’s common stock. Therefore, effective at the opening of business on Wednesday, December 19, 2007, the Company’s common stock will be suspended from trading on the Nasdaq Global Market, and will be subsequently delisted.

As previously disclosed by the Company, by a decision dated November 30, 2007, the Board of Directors of Nasdaq (the “Nasdaq Board”) gave the Company until December 17, 2007 to file its past due periodic reports with the SEC and regain compliance with Nasdaq’s listing requirements contained in Nasdaq Marketplace Rule 4310(c)(14). In its decision, the Nasdaq Board noted that the Company has been out of compliance with Nasdaq Marketplace Rule 4310(c)(14), which requires the timely filing of reports with the Securities and Exchange Commission (“SEC”), for a period of one year from the final due date of the Company’s annual report on Form 10-K for the fiscal year ended September 30, 2006 (the “2006 10-K”). On December 11, 2007, the Company filed the 2006 10-K with the SEC, which was within one year from when the 2006 10-K was due. The Company continues to work diligently to finalize its remaining delinquent SEC filings and had requested that the Nasdaq Board give the Company additional time to file its quarterly reports on Form 10-Q for the first three quarters of fiscal 2007 and its annual report on Form 10-K for the fiscal year ended September 30, 2007. The Nasdaq Board declined to reconsider its prior decision despite the recent filing of the Company’s 2006 Form 10-K. The Company also moved the SEC to stay the Nasdaq Board’s decision and on December 18, 2007 the SEC notified the Company that it denied the Company’s motion.

The delay in filing the Company’s periodic reports arose from the length of time it took to complete the internal investigation by a Special Committee of the Company’s Board of Directors into historical stock option granting practices and the resulting restatement. The Company intends to file its remaining past due periodic reports as soon as possible and is committed to regaining compliance with all filing requirements. The Company intends to relist its common stock on a national exchange as soon as practicable and expects it will be in a position to do so shortly after its annual meeting of stockholders scheduled for March 19, 2008. The Company has previously announced that it expects to file its delinquent Forms 10-Q no later than January 31, 2008 and expects to file its Form 10-K for the fiscal year ended September 30, 2007 shortly thereafter.

The Company anticipates that its common stock will be quoted on the Pink Sheet Electronic Quotation Service automatically and immediately after Nasdaq suspends trading. The Company expects that the trading symbol of its common stock will remain the same (COHR). Information about the Pink Sheets can be found at its Internet website www.pinksheets.com.

The Company has previously issued several press releases and filed several reports with the SEC including reports on Form 8-K, and investors are encouraged to read these in their entirety for discussion of the delay in the Company’s filings.

Forward Looking Statements
This press release contains forward-looking statements, as defined under the Federal securities laws. These forward-looking statements include statements regarding Coherent's expectation regarding the timing of filing its delinquent SEC filings, its intention of relisting its common stock on a national exchange, the timing thereof, and its common stock trading on the “Pink Sheets”. These forward-looking statements are not guarantees and are subject to risks, uncertainties and assumptions that could cause the timing or effect of such statements to differ materially and adversely from the timing expressed in the forward-looking statements in this press release. Factors that could cause actual results to differ materially include risks and uncertainties, including but not limited to risks associated with the completion of the audit, review and preparation of our SEC filings. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as to Coherent's expectations as of the date hereof. Coherent undertakes no obligation to update these forward-looking statements as a result of events or circumstances after the date hereof or to reflect the occurrence of unanticipated events. The trading of our common stock over the counter may negatively impact the trading price of our common stock and the levels of liquidity available to our stockholders. In addition, the trading of our common stock over the counter would materially adversely affect our access to the capital markets and our ability to raise capital through alternative financing sources on terms acceptable to us or at all. Securities that trade over the counter are no longer eligible for margin loans, and a company trading over the counter cannot avail itself of Federal preemption of state securities or "blue sky" laws, which adds substantial compliance costs to securities issuances, including pursuant to employee option plans, stock purchase plans and private or public offerings of securities. Our delisting from the Nasdaq Global Select Market, may also have other negative implications, including the potential loss of confidence by suppliers, customers and employees and the loss of institutional investor interest in our company.

Santa Clara, Calif., December 14, 2007 – The new MATRIXTM 355 BE from Coherent, Inc. (Santa Clara, CA) (Nasdaq: COHR) is a frequency-tripled DPSS (diode pumped solid state) laser that delivers a unique combination of low output noise and low beam divergence. Specifically, this is the first OEM UV laser to incorporate an integral beam expander within the sealed laser head, which results in an output beam diameter (1/e2) of 2.2 mm and a divergence of only 0.5 mrad. This low divergence is an advantage in many OEM applications, especially those having particularly long beam delivery paths or requiring high NA focusing. The new laser is offered with a choice of 1 or 2 watts of average power and pulse repetition rates as high as 60 kHz.

As with other MATRIX lasers, the MATRIX 355 BE is fully RoHS compliant and backed by an 18 month/10,000 hour warranty. The MATRIX 355 BE is optimized to deliver long-lifetime operation for precision applications in materials processing and marking, such as stereolithography (rapid prototyping), LCD/FPD titling, memory repair, thin film ablation, internal glass marking, cold marking of plastics and semiconductors, and semiconductor scribing.
