摘　　要：基于InGaSb/AlGaAsSb材料体系,制备出了一款高性能的镀膜激光器。为了性能对比,同时制备了未镀膜激光器。未镀膜的器件在注入电流为3.0A时,室温连续模式下的输出功率达到300mW,最大插头效率为8.3%。镀膜器件在注入电流为2.6A时,室温连续模式下的输出功率达到380mW,最大插头效率为15.6%;另外,在0.3~2.4A的注入电流范围内,镀膜器件的插头效率均大于10.0%,激射波长均在2.0μm附近。The coated laser with a high performance is fabricated based on the InGaSb/AlGaAsSb material system,and simultaneously the laser without facet coating is also fabricated for a performance comparison.The laser without facet coating working in the continuous-wave（CW）mode and under room temperature（RT）shows an output power of up to 300 mW at the injection current of 3.0 Aand the maximum wall plug efficiency（WPE）is 8.3%.The laser with facet coating working in the CW mode and also under RT exhibits an output power of up to 380 mW at the injection current of 2.6 Aand the maximum WPE is 15.6%.The WPE of the coated laser is always above 10.0%and the emission wavelength is around 2.0μm at the injection current range of 0.3-2.4 A.
