摘　　要：从半导体激光器光注入调制理论出发,分析了不同光注入条件下的频率调制特性。讨论了几种半导体激光器光频调制方法,并介绍了其实验装置。采用这些光频调制方法,能使光频调制中光强变化的影响大大减小,可用于纳米级的高精度干涉测量系统中。According to the theory of light injection in laser diode, the characteristics of the frequency modulation under different injection conditions are analyzed. Some schemes of frequency modulation used to reduce the influence of light-intensity modulation and realize nanometer-accuracy interferometer measurement are put forward, and their operation principle is discribed.
