DFB QCL laser的特點(diǎn):DFB QCL laser DFB型量子級(jí)聯(lián)激光器,用于氣體光譜研究或者氣體跟蹤,具有優(yōu)良的單模特性,窄線寬,以及通過溫度或者電流調(diào)節(jié)波長等特性??晒ぷ饔谶B續(xù)或者脈沖模式。
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.
