Frequency-Tripled DPSS Laser
Aug 2008
Coherent Inc.Request Info
SANTA CLARA, Calif., Aug. 13, 2008 – Coherent Inc., has introduced the new Matrix 355 BE, a frequency-tripled DPSS (diode-pumped solid-state) laser that delivers a unique combination of low output noise and low beam divergence. 

Coherent-Matrix-355-BE.jpgSpecifically, 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 W of average power and pulse repetition rates as high as 60 kHz. 

As with other Matrix lasers, the 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.

beam expander
A system of optical components designed to increase the diameter of a radiation beam. Usually an afocal system.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
