Short Wavelength Laser manages micromachining applications.

Press Release Summary:



Q-switched AVIA 266-1500 diode-pumped, all-solid-state, 266 nm UV laser has average power of 1.5W at 20 kHz, making it suitable for micromachining sensitive materials such as glass, silicon and microelectronic materials, and thin-film removal. It can produce spot sizes as small as 5 microns and perform micromachining without producing collateral thermal damage. Device is pumped by 2 field-replaceable, aluminum-free active area (AAA) diode modules.

Coherent Debuts Industry's Highest Power Highest Repetition Rate 266 nm Laser


Santa Clara, Calif., January 23, 2002 - Coherent Laser Division (CLD) (Santa Clara, CA) (Nasdaq: COHR) introduces the AVIA 266-1500, the most reliable high repetition rate 266 nm laser available today. The AVIA 266-1500 is a Q-switched, diode-pumped, all-solid-state, 266 nm UV laser based on the field-proven technology platform established in Coherent's AVIA 355 series lasers. With specified average power of 1.5W at 20 kHz and a TEM00 beam, the new AVIA 266-1500 is ideal for a wide range of micromachining applications, including glass processing and thin-film removal.

"Our new AVIA 266-1500 offers a key benefits for micromachining sensitive materials such as glass, silicon and microelectronic materials," said Paul Somerville, AVIA product line manager.

"The short, 266 nm wavelength of the AVIA 266-1500 gives you the highest resolution available from a solid-state laser for micromachining. It can produce spot sizes as small as five-microns-something that other lasers just can't do. It also has the capability of micromachining without producing collateral thermal damage, which is especially important when processing sensitive materials."

Optimized for manufacturing environments, the AVIA 266-1500 features single-shot to 100 kHz operation and a robust industrial package designed for a field-installed lifetime of over 10,000 hours. AVIA is pumped by two of Coherent's field-replaceable, aluminum-free active area (AAA) diode modules, which demonstrate outstanding lifetimes even under the most extreme

"The AVIA 266-1500 expands the capabilities of solid-state, pulsed UV lasers," said Somerville. "It's ideal for demanding industrial applications where excimer lasers are currently being used. Yet it exceeds their performance since it can be focused more precisely and cleanly, and it has a much lower cost of ownership. The performance of this AVIA extends the micromachining capabilities of solid-state, pulsed, UV lasers, while its small size and high reliability make it practical for applications where deep UV couldn't be used before."

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.
