| 摘 要： | 稳定激光频率是进行高分辨光谱、精密测量的前提条件.文章利用微波锁相频率计数器,用一台已锁定的激光器,通过拍频信号将另一台激光器锁定在需要的频率差范围内(10 MHz～20 GHz),达到3～4 h稳频的目的,为研究原子系统中的电磁诱导透明光谱、拉曼光谱、四波混频等提供实验依据.

| Abstract: | Technology of achieving stable laser frequency plays an important role in the application of high precision measurement and high fine spectrum.In this paper,we phase-locked a laser for 3 to 4 hours to the other laser by the signal of beat frequency between two lasers,based on the instrument:Source locking CW microwave frequency counter.This work enables us to investigate the electromagnetically induced transparency spectroscopy,Raman spectroscopy and four-wave-mixing in atomic system. |
