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.

本文首先回顧了PDH技術的原理和特點,從理論上分析了電光相位調制的調制頻率、調制度對光學諧振腔相位調制光外差光譜色散型譜線線型和鑒頻曲線斜率的影響;討論了Fabry-Perot(F-P)腔的線寬、模式匹配以及穩定度等因素對光外差光譜線型及對激光穩頻的影響,并由此設計了一種合適的F-P腔用于He-Ne激光器頻率鎖定。
