High Efficiency, High Reliability Laser Diodes at JDS Uniphase

摘要

Laser diodes and bars with high efficiency, power, and reliability are critical for a wide variety of applications includingdirect material processing and pumping high power and efficient fiber lasers and solid state lasers. We present progresstowards the 80% power conversion efficiency goal of the DARPA Super High Efficiency Diode Sources (SHEDS)program. Currently, laser bars using JDSU SHEDS technology achieve as high as 72.7% total power conversionefficiency at room temperature and 80W operating power.
