本文叙述了利用氦氖激光频率分裂技术研制波长为１１５０ｎｍ的可调谐的红外光拍发生器的实验及其结果，结果表明这种红外光拍发生器拍频的大小可以从４０ＭＨｚ到几百兆赫兹。同时，我们也对其它特性，如模竞争等进行了研究
This paper describes the experiment and results of a tunable infrared light polarizer with a wavelength of 1150 nm by using the He-Ne laser frequency splitting technique. The results show that the beat frequency of the infrared light polarizer can range from 40 MHz to several hundred megahertz . At the same time, we also study other characteristics, such as modal competition
