摘　　要：根据光反馈自混合干涉效应的基本理论模型,通过求解适度反馈下的相位方程,讨论了半导体激光器的运行模态及特性,并搭建自混合干涉测量实验系统进行实验研究,与模拟仿真结果进行对比分析。在此基础上,实验研究表明扬声器的振幅与驱动电压成良好的线性关系。The operating states and features of semiconductor lasers are discussed based on basic theory models of laser feedback self-mixing interference effect and phase equations at moderate feedback condition. Measurement experiment systems of self-mixing interference are built for experiment research, which are com- pared and analyzed with the results of simulation. Based on this, the experiment research result shows that a good linear relationship between amplitude of loudspeaker and driving voltage is formed.
