Coherent Introduces 10W, Diode-Pumped, Industrial UV Laser

AVIA 355-X Provides Low Cost of Ownership and High Throughput for Materials Processing, Microvia Drilling Applications

Santa Clara, Calif., February 25, 2003 - Coherent, Inc. (Santa Clara, CA) (Nasdaq: COHR) introduces the latest addition to its successful AVIA product family, the AVIA 355-X. The AVIA 355-X is a Q-switched, diode-pumped, solid-state industrial UV laser that delivers 10W of 355-nm light at 60 kHz. It is ideal for microvia drilling and a variety of other high-speed materials processing applications.

"With the AVIA's 10W of average power, manufacturers will see a significant increase in throughput," said Paul Somerville, AVIA product line manager. "And our new HGX(TM) harmonic generation technology results in a dramatic increase in third harmonic crystal lifetime, meaning less down time and lower cost of ownership when compared to similar lasers on the market today."

The AVIA 355-X has twice the third harmonic crystal lifetime of previous generation 355-nm lasers-a result of Coherent's proprietary HGX(TM) harmonic generation technology. In addition, the efficiency of the AVIA 355-X allows it to achieve 10W of 355 nm output with only two diode modules. Other high-power UV lasers require as many as four pump modules. "With half as many diodes as previous generation lasers, your risk of diode failure is significantly reduced," added Somerville.

Optimized for manufacturing environments, the AVIA 355-X features single shot to 100 kHz operation, and a robust industrial package designed for a field-installed lifetime of over 20,000 hours. The AVIA 355-X is pumped by Coherent's field-replaceable, aluminum-free active area (AAA) diode modules, which demonstrate outstanding lifetimes even under the most extreme conditions.

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 and scientific markets.
