摘要

利用光谱和空间分辨红外显微技术研究了半导体激光二极管的稳态内部物理。通过对长波体激光器和MQW CMBH Fabry-Perot InGaAsP/InP激光器在1.48/spl mu/m激光下的纵向腔内自发发射曲线进行成像，我们观察到在激光阈值以上的纵向空间孔燃烧。

Imaging spatial and spectral inhomogenous spontaneous emission in high power semiconductor lasers

Spectrally and spatially resolved infrared microscopy has been used to study the steady state internal physics of semiconductor laser diodes. By imaging the longitudinal intra-cavity spontaneous emission profiles of both long wavelength bulk and MQW CMBH Fabry-Perot InGaAsP/InP lasers lasing at 1.48/spl mu/m, we observed the longitudinal spatial hole burning above the lasing threshold.
