我们报道了一个50 mW的连续波量子级联激光器（QCL）在9.2微米范围内的工作，锁相到具有可调谐频率偏移的单模CO(2)激光器。QCL的宽自由运行发射光谱（3-5 MHz）被强烈地缩小到千赫兹范围，使其适合于高分辨率分子光谱。
We report the operation of a 50 mW continuous-wave quantum cascade laser (QCL) in the 9.2 microm range, phase locked to a single-mode CO(2) laser with a tunable frequency offset. The wide free-running emission spectrum of the QCL (3-5 MHz) is strongly narrowed down to the kilohertz range, making it suitable for high-resolution molecular spectroscopy.
