Paper Abstract

Degradation modes of high power GaAlAs infrared lasers in accelerated life tests were investigated. Two modes were observed: gradual and rapid degradation. The latter degradation mode suddenly occurred after the gradual degradation mode. In order to clarify the cause of the rapid degradation, we compared them with artificially stressed degradation modes.
