heterodyne spectroscopy

We also analyze the influence of finesse,mode matching and stability of the F-P cavity on the optical heterodyne spectrum and frequency stability of laser.

本文首先回顾了PDH技术的原理和特点,从理论上分析了电光相位调制的调制频率、调制度对光学谐振腔相位调制光外差光谱色散型谱线线型和鉴频曲线斜率的影响;讨论了Fabry-Perot(F-P)腔的线宽、模式匹配以及稳定度等因素对光外差光谱线型及对激光稳频的影响,并由此设计了一种合适的F-P腔用于He-Ne激光器频率锁定。
