摘要

应用MOVPE研制出梯度折射率分别限制GaAs/AlGaAs单量子阱激光器

室温单面连续输出光功率超过500mW

激射波长为820.3nm

并讨论了注入电流和温度改变对波长的影响.

Abstract

The high power linear graded-index separate-confine-heterostructure signle-quantum-well GaAs/AlGaAs lasers have been grown and fabricated by MOVPE method.The maximum continue wave output optical power is up to 500mW for the lasers with 300μm wide stripe and 600μm cavity length.Threshold current is 137mA and emitting wavelength is 820.3nm at room temperature for continue wave operation.The measured vertical and parallel divergance angle are 4.5°and 38.2°

respectively.That is the advantages of graded-index separate-confine-heterostructure

thus it can get a higher efficiency in the application of pump solid lasers and fiber output.
