DFB QCL laser DFB型量子级联激光器，用于气体光谱研究或者气体跟踪，具有优良的单模特性，窄线宽，以及通过温度或者电流调节波长等特性。可工作于连续或者脉冲模式。

For gaz spectroscopy or trace gaz detection, single-mode, well-defined narrow linewidth lasers with precise tunability are required. For this purpose, quantum cascade lasers are built with a grating in the cavity that allow to exhibit an excellent single-mode behavior. DFB-QCLs can be precisely tuned with temperature (slow tuning) or current (quick tuning), and deliver a reasonable amount of output power.
