外光反馈对半导体激光器性能的影响，从激光腔外部的反射器返回一部分激光输出。本文给出了单模激光器的实验观测结果，并根据复合腔激光器模型进行了分析，发现该模型能解释实验结果的基本特征。特别是，它已被证明，与外部反馈的激光器可以是多稳态的，并显示滞后现象，类似于非线性法布里-珀罗谐振腔。它还表明，注入激光器的动态特性显着影响外部反馈，这取决于返回光和激光二极管内部的字段之间的干涉条件。
Influences on the semiconductor laser properties of external optical feedback, i.e., return of a portion of the laser output from a reflector external to the laser cavity, have been examined. Experimental observations with a single mode laser is presented with analysis based on a compound cavity laser model, which has been found to explain essential features of the experimental results. In particular, it has been demonstrated that a laser with external feedback can be multistable and show hysteresis phenomena, analogous to those of non-linear Fabry-Perot resonator. It has also been shown that the dynamic properties of injection lasers are significantly affected by external feedback, depending on interference conditions between returned light and the field inside the laser diode.
