光纤干涉法监测He-Ne激光器的频率漂移

The measurement of frequency-shift of He-Ne laser by means of an optical fiber interferometer

本文介绍了液芯光纤干涉方法测量He-Ne激光器腔长的微小伸长,频率漂移的原理,实验条件,实验装置及实验结果。

In this paper, a method and an experiment of measuring the frequency-shift of a He-Ne laser are described.The relationship of the mini-extension of the cavity length and frequency shift is discus- sed in detall.In the experiment, a interferometer with liquid-core op- tical fiber is used.
