多段式半导体激光器的端面输出谱

Expression of the Output Spectrum From Multi Segmented Semiconductor Lasers

在充分考虑激光源于放大自发辐射、而自发辐射可能产生于半导体激光器（LD）有源层中的各点等物理事实的基础上，我们采用射线法、以递推公式的形式导出院多段式半导体激光器的输出谱的解析表达式，并对某些常见的情况进行了简单扼要地讨论。

： Taking into account the facts that the laser radiation is developed from the amplified spontaneous emission ASE  and the ASE may be generated at any point of the active layer of the semiconductor laserLD， the ray trace method has been used to derive the expression of the output spectrum from a multi segmeneted seiconductor laser． In addition， brief descriptions have been given to cases often encountered．
