摘要
介绍了布里渊光纤环形激光器拍频法、差拍法、零拍法和光纤环法4种超窄激光线宽的测量方法。通过比较,给出了4种方法在分辨率、激光线宽和线型效应等方面的优缺点,根据这些优缺点,指出了每种方法的适用范围。
Four methods of measuring Ultra-Narrow Laser line-width using Brillouin fiber ring laser beat,DSHI,homodyne,and LC-DSHI.The characters of laser line-width resolution and the relationship between beat spectrum and laser line-width were compared with each method.Then merits and demerits and applicability of these methods were pointed out.
