Taking an external cavity laser diode (ECLD) as an example, calculations indicate that the perturbation analysis may become invalid under loss modulation.

以可调谐双稳外腔半导体激光器(ECLD)为例，指明了在损耗调制下，扰动近似分析可能会失效。

My paper is including two parts: the design and implement of the external cavity laser diode (ECLD) current source and the research of network data disaster recovery system.

课题工作内容主要分为：外腔半导体激光器用恒流电路的设计与实现和基于网络的远程数据备份容灾方案两大部分。

A tunable diode laser was used to probe the gain spectra and profile of a supersonic COIL. The cavity temperature was obtained based on Doppler broadening.

利用可调谐二极管激光器做探测光源，测量了超音速氧碘化学激光的增益谱线和增益线型。根据多普勒展宽，间接得到了超音速氧碘激光器的腔内温度。
