Abstract

This paper gives an overview of recent development of high-efficiency 50-W CW TE/TM polarized 808-nm diode laser bar at Lasertel. Focused development of device design and MBE growth processes has yielded significant improvement in power conversion efficiency (PCE) of 50-W CW TE/TM polarized 808-nm laser bars. We have achieved CW PCEs of 67 % to 64 % at heat-sink temperature of 5 °C and 25 °C, respectively. Ongoing life-testing indicates that the reliable powers of devices based on the new developments exceed those of established, highly reliable, production designs.
