Coherent Combines Excellent Beam Quality with Compact Package in New 30W CO2 OEM Laser

Santa Clara, Calif., July 2, 2002 - Coherent, Inc. (Santa Clara, CA) (Nasdaq: COHR) unveils a new low-power CO2 laser that features excellent beam quality and a very small footprint. Called the GEM-30(TM), this OEM laser provides more than 30W of output power at 10.55- to 10.63-micrometer with a greater than 98% TEM00 spatial mode and M²<1.2 beam quality. It is ideal for marking, engraving and desktop manufacturing.

The GEM-30 was built using the same laser cavity as its predecessor, the GEM-25, but is based on an innovative platform where the power supply RF driver is integrated into the same housing as the laser head. This results in a compact, robust package that can operate in the most demanding environments. The GEM-30 provides 20% higher power than its predecessor and comes in a single, compact package, providing ease of integration and enabling previously unattainable desktop-sized, high-throughput marking and engraving systems.

"The advantages of the GEM-30 are numerous. You get the agility and ease of integration that comes with a compact, integrated platform, as well as the reliability and dependability that
comes with using a field-proven technology," said Ron Straayer, product manager at Coherent. "Plus, you get a laser with higher power levels at a lower price point."

Available in both air- and liquid-cooled models, the GEM-30 measures just 357 mm x 92.46 mm x 139.6 mm (14.06" x 3.64" x 5.49") for the air-cooled version; 357 mm x 92.46 mm x 92.79
mm (14.06" x 3.64" x 3.65") for the liquid-cooled version. The GEM-30 has a superior rise time of less than 60 microsec. It runs on 48 VDC (12 amps) and has a RJ-45 Ethernet connector. Mounting brackets are also available.

Originally founded in 1994 as DeMaria ElectroOptics Systems Inc. (DEOS), DEOS was acquired by Coherent Inc. in April 2001. Coherent-DEOS designs and manufactures carbon-dioxide lasers used in materials processing, electronics packaging, and research applications. The acquisition further enhanced Coherent's CO2 laser portfolio, making the company the only
manufacturer to offer a line of sealed CO2 lasers ranging in power from 25W to 500W.

Founded in 1966, Coherent, Inc. is a Standard & Poor's SmallCap 600 company and a world leader in providing photonics-based solutions to the commercial, scientific, and telecom markets.
