量子阱半导体激光器的光束质量

OPTICAL BEAM QUALITY FACTORS OF QUANTUM WELL SEMICONDUCTOR LASERS

本文给出了一种非截取地收集非傍轴激光束 ,并把它变换成傍轴光束的方法 ,将之运用到量子阱半导体激光器的实验中发现了一些重要的现象 .经过测量和计算得到它垂直于结方向的等效光束质量原子 M2y 明显小于 1 。

An approach to non truncatedly collect non paraxial semiconductor laser beam and transform it into paraxial one is given.By using this way,some novel phenomena are revealed in the experiments of a common strained multiple quantum well laser diode.The results show that M 2 y in vertical direction is obviously smaller than 1.This discovery will bring the study and applications of semiconductor lasers to a new stage.
