Oclaro to Present Diode Bar Results

SAN JOSE, Calif., Jan. 18, 2010 – Oclaro Inc., an optical components provider for industrial applications, will present its results on high-power laser diode bars in Quasi Continuous Wave (QCW) operation at Photonics West on Jan. 26 in San Francisco.

Demonstrating significant performance improvements, the company’s results show its laser diode bars deliver output powers of more than 550 W at 200 us pulse width and wall plug efficiency levels > 65%. The results will be presented by Jurgen Muller, lead design engineer for Oclaro.

“These new results reflect Oclaro’s commitment to continually raise the bar on performance and functionality to help our customers win in the market,” said Norbert Lichtenstein, director of research and design at Oclaro. “We were very pleased to see the scalability of our high-power CW bar design to pulsed operation modes over a wide wavelength and temperature range, and this will be a very valuable feature in the solid-state laser pumping, laser illumination, direct diode material processing and medical markets.”

The data to be presented will comprise results for an extended wavelength range from 808 to 1080 nm at temperatures as high as 70 °C.

Similar to all its high power laser products, the front facet of the bar is protected against catastrophic optical damage by its E2 mirror passivation process. Telecom grade AuSn (gold tin) hard solder makes the product suitable for demanding industrial and defense applications in CW and hard-pulse operation mode.
