Santa Clara, Calif., June 24, 2003 - 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-40, this OEM laser provides more than 40W of output power at 10.55- to 10.63-µm with a greater than 98% TEM00 spatial mode and M²<1.2 beam="" quality.="" the="" gem-40="" is="" ideal="" for="" medium-="" to="" high-volume="" marking,="" engraving="" and="" desktop="">

Designed for OEM customers who need added power in an easy-to-integrate, compact package, the new GEM-40 has the same laser cavity as its predecessor, the GEM-30, but with 35% higher rated power. "The advantages of the GEM-40 are obvious. 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 for Coherent. "The addition of the GEM-40 gives OEMs of the GEM-30 a convenient and cost-effective approach to service their customers who need higher power levels in the same small package."

Available in both air- and liquid-cooled models, the GEM-40 measures just 412 mm x 91 mm x 140 mm (16.2 x 3.6 x 5.5 inches) in both the air-cooled and water-cooled versions. The GEM-40 features a rise time of less than 60 µsec. It runs on 48 VDC (12 amps) and has a RJ-45 Ethernet connector. Mounting brackets are also available.

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