A simple method for laser frequency stabilizing by a temperature-tuned Fabry-Perot etalon is reported. The etalon is a plano-convex lens that permits tuning the length and refractive index via controlling the temperature for shifting wavelengths in the region of 852 nm, with a transmission spectral linewidth of ∼72.5 and free spectral region of ∼16. Using this scheme, arbitrary frequency locking of a laser with an adjustable frequency resolution of 2.34/ is realized, and MHz-level long-term stability is demonstrated.
报道了一种利用温度调谐法布里-珀罗标准具实现激光频率稳定的简单方法。该标准具是一个平凸透镜，通过控制温度来调节长度和折射率，从而在852nm波长区域移动波长，其透射光谱线宽约为72.5，自由光谱范围约为16。利用该方案，实现了频率可调分辨率为2.34/的激光的任意频率锁定，并证明了其兆赫兹级的长期稳定性。
