摘要

为了改善9xx nm高功率半导体激光器的性能，对n包层和p包层的掺杂分布进行了调整，以减小激光器的内部损耗。同时为了减小有源区载流子的泄漏，在有源区和波导层之间引入了高能量带隙GaAsP。设计并制作了内部损耗为1.25 cm

Abstract

To improve the performance of 9xx nm high power semiconductor lasers

the doping profile of n-cladding layer and p-cladding layer is adjusted to reduce the internal loss. A high energy band gap GaAsP was introduced between the active region and the waveguide layer to reduce the leakage of carriers in the active region. A broad area laser with internal loss of 1.25 cm is designed and fabricated. The device with maximum output power of 26.5 W is obtained. The maximum electrical-optical power conversion efficiency is 72.4%

which is obtained when the output power is 10.5 W. The slope efficiency is 1.16 W/A.
