Abstract :
A 0.3 W operation for a single emitter broad area red laser at 45degC was achieved, for the first time, and a highly reliable 25 emitter array operation of 6.6 W at 25degC. The laser array is composed of 25 broad stripe lasers with a stripe pitch of 400 mum. The operation current, operation voltage, slope efficiency, emission wavelength and the energy conversion efficiency of the laser diode were obtained. Lifetime test was performed under constant current mode.
