高温连续输出AlGaAs大功率单量子阱激光器的工作特性
High-Power, High-Temperature Operation of AlGaAs Single Quantum Well Lasers
【摘要】 本文介绍了利用MBE方法生长的大功率AlGaAs单量子阱激光器的高温工作特性.激光器的室温连续输出功率达到2W.在95℃高温连续工作状态下,其输出功率仍可达到500mW的水平.器件的特征温度高达185K(35~85℃)及163K(85~95℃).同室温相比,器件在95℃的工作条件下,其功率输出的斜效率下降了23%.
【Abstract】 High power AlGaAs single quantum well (GRIN-SCH) lasers grown by MBE have been investigated at high temperature. We have demonstrated the GRIN-SCH lasers capable of CW operation up to 2W at room temperature and 500mW at 95℃. The laser has characteristic temperature (T0) of 185K (35~85℃ ) and 163K (85~95℃). Compared with the operation at room temperature, the slope efficiency is decreased by 23% at 95℃.
