摘要: 应用空心阴极放电管观测铷D2线的光电流谱,发现谱线中部有凹陷出现。对凹陷出现的原因进行了分析和研究。利用此现象,将半导体激光器(0.7800μm)频率锁定于谱线凹陷的中央。

Abstract: Find dips in the centers of atomic lines when observing high-resolution optogalvanic spectra of Rb D2 in hollow cathode lamp. The origin of these dips is analysed and studied. The frequency of a semiconductor laser(0.7800 μm) is locked to the center of a dip using this phenomenon.

Key words: optogalvanic spectrum, Rubidium atomic spectrum, Laser frequency stabilization
