我们提出了一个系统，它使用从衍射光栅的光反馈，以提供主要的控制二极管激光器的频率调谐，并采用同时从窄带法布里-珀罗腔的光反馈，以减少线宽。利用一种新的技术实现了对来自衍射光栅和窄带腔的光反馈频率的电子锁定。线宽的减小被测量为在Cs饱和吸收线侧看到的频率噪声的减小。与单独使用光栅反馈获得的频率噪声相比，来自窄带腔的光反馈的存在将频率噪声降低了3倍。
We present a system which uses optical feedback from a diffraction grating to provide primary control over the frequency tuning of a diode laser, and employs simultaneous optical feedback from a narrowband Fabry–Perot cavity to reduce the linewidth. The frequencies of the optical feedback from the diffraction grating and narrowband cavity are electronically locked using a novel technique. The reduction in the linewidth is measured as a reduction in the frequency noise seen on the side of a Cs‐saturated absorption line. The presence of optical feedback from the narrowband cavity reduces the frequency noise by a factor of 3 compared to the frequency noise obtained using the grating feedback alone.
