Considering the experiment in practice, we analyze the laserfeedback interference at the condition of multiple external cavities.
考虑在实际实验中的情况，分析了多外腔条件下的自混合干涉效应。

By means of pulse injection, the relation between lasing wavelength and chip temperature of distributed feedbacklaser (DFB-LD) has been obtained.
利用脉冲注入法测量了分布反馈激光器(DFB - LD)芯片温度与激射波长的关系。
