Paper 9348-19: Reliability study of high brightness multiple single emitter diode lasers

Presenter: Thomas Yang 
 

High brightness pumps based on multiple single emitters offer significant advantages in thermal management and reliability for pumping high-power fiber lasers. The lifetime of the high brightness pump lasers are from the laser diode chips and the multi-emitter packages. In this study, we optimized the chip bonding processes for various chips including 9xxnm 10W-20W, 1470nm 6W types which were from various suppliers around the world, and achieved suitable chip bonding processes to produce high performance and reliable chip-on-submount. Then, in this paper, a series of accelerated life tests were performed on 2-emitter to 7-emitter packages with 9xxnm/105um fiber coupled modules. The MTTF of these modules exceeds 100k hours. Finally, we present a separate reliability study on wavelength stabilized 976nm fiber coupled diode.
