Increasing the reliable operation power of laser diodes enables a wide range of telecom and industrial applications. In this paper, such high power laser diode technologies as the suppression of catastrophic optical damage, improved effi ciency, and increased emitters are reviewed. Developed high power laser diode products are also discussed. For 9xx nm laser diodes, we present 15-W reliable operation from a 95 μm wide emitter and 60-W operation from a mini-bar with 7 emitters and 100 μm emitter width.
