Abstract

Reliability of high-power semiconductor lasers can be underestimated because of imperfect bonding and improper mounting. The C-mount package of Cu material is replaced with CuW material and high power laser chips are bonded above without AlN submount. For the burn-in test, liquid-metal alloy is applied between C-mount and heatsink to improve thermal contact. The estimated lifetime of 4 W, 808 nm lasers is therefore greatly increased to over 3600 hours.
