CAMBRIDGE, Mass. – July 28, 2008 – Applied scientists at Harvard University in collaboration with researchers from Hamamatsu Photonics in Hamamatsu City, Japan, have demonstrated, for the first time, highly directional semiconductor lasers with a much smaller beam divergence than conventional ones. The innovation opens the door to a wide range of applications in photonics and communications. Harvard University has also filed a broad patent on the invention.

Spearheaded by graduate student Nanfang Yu and Federico Capasso, Robert L. Wallace Professor of Applied Physics and Vinton Hayes Senior Research Fellow in Electrical Engineering, all of Harvard's School of Engineering and Applied Sciences (SEAS), and by a team at Hamamatsu Photonics headed by Dr. Hirofumi Kan, General Manager of the Laser Group, the findings were published online in the July 28th issue of Nature Photonics and will appear in the September print issue.

Santa Clara, Calif., December 14, 2007 – The new MATRIXTM 355 BE from Coherent, Inc. (Santa Clara, CA) (Nasdaq: COHR) is a frequency-tripled DPSS (diode pumped solid state) laser that delivers a unique combination of low output noise and low beam divergence. Specifically, 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 watts of average power and pulse repetition rates as high as 60 kHz.

As with other MATRIX lasers, the MATRIX 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.
