摘要
基于Hnsch-Couillaud（H-C）频率锁定技术，通过理论计算得到了用于实现激光到环形腔频率锁定的误差信号，并在实验上利用1583 nm激光与腔内含有KTP晶体的蝶形环形腔对激光到环形腔的频率锁定进行了实验研究，理论结果与实验结果相符。该方案与传统方法相比，大大简化了实验装置，而且操作方便灵活，可以广泛地应用到激光技术、污染气体检测等众多领域。
Abstract
The error signal used for stabilizing a laser frequency to an external bowtie-shaped ring cavity is analyzed theoretically based on the Hnsch-Couillaud frequency locking technique. In the experiment, the frequency of a 1583 nm fiber laser is locked to the longitude mode of a bowtie-shaped ring cavity with a KTP crystal inside it. The setup of this locking scheme is simple, and the technique is rather easy to operate, so it can be widely used in the laser technology, trace gas detection or other areas.
