半导体激光器的噪声和带宽的测量

Measurement of Noise and Bandwidth of Semiconductor Lasers

半导体激光器广泛地应用于光学测量、激光雷达、机载陀螺仪、信息处理、光通信、激光光谱和激光抽运原子频标等领域。在这些应用中半导体激光器的噪声和带宽是十分重要的参数,必须进行测量。本文详细地介绍了在激光抽运铷频标研制过程中激光器的噪声和带究的测试方法及实验结果。

Semiconductor lasers are widely used in such areas as optical mea- surement,laser radars,air-borne gyroscopes,optial communications,laser spec- troscopy,and laser pumped atom frequency standard,etc.In these applications, noise and bandwidth are of great importance for the lasers.This paper gives a detail description of the measurement of noise and bandwidth along with the ex- perimental results.
