Oclaro to Present Industry-Leading Results of >550W for QCW Operation Laser Diode Bars
Oclaro, Inc. a provider of optical components for industrial applications, will be presenting its latest results on high-power laser diode bars in Quasi Continuous Wave (QCW) operation at the upcoming Photonics West event in San Francisco, Calif.
Demonstrating significant performance improvements, the new results show Oclaro laser diode bars delivering output powers of more than 550W at 200us pulse width and wall plug efficiency levels of more than 65%. These results will be presented by Jurgen Muller, a Lead Design Engineer for Oclaro, at Photonics West on Jan. 26 at The Moscone Center in room 103/104 at 6:00pm.
"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 R&D 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 new dataset Oclaro will be presenting comprises results for an extended wavelength range from 808nm to 1080nm at temperatures as high as 70 degrees C. For 808nm laser diodes on conductively cooled standard CS type assembly up to 580W were measured at 500us and about 1 % duty cycle. Similar results were achieved with 9xxnm laser diode bars. The latter were also assembled on a compact sandwich assembly with a footprint of 12mm by 10mm only and a height of 4.7mm. The device was operated up to >400W at 6% duty cycle and 25 degrees C.
Similar to all Oclaro high power laser products, the front facet of the bar is protected against Catastrophic Optical Damage by the Oclaro 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.
Oclaro's Presence at Photonics West and LASE 2010
Oclaro will be showcasing its new high-power laser diodes at Photonics West (booth #1101.) The company will also be presenting five technical papers at the associated Symposium LASE 2010. Below is a listing of all five papers, the first of which is described above in this press release.
· 'CW to QCW power scaling of high-power laser bars'
· 'Eye safe high-power laser diode in the 1410-1550 nm range'
· 'Reliable operation of 8xx mini-bar-based hermetic modules'
· 'Extending the wavelength range in the Oclaro high-brightness broad area modules'
· 'Novel single-mode fiber coupled broadband seed source for pulsed fiber laser systems'
