| 中文摘要: |
| 在冷原子干涉实验中需要用激光冷却并操控原子，因此对半导体激光器频率的稳定性要求较高。由于半导体激光器本身线宽较大，功率稳定性差，还可能产生慢漂和跳模等现象，故需对半导体激光器进行稳频。本文介绍了饱和吸收谱稳频、波长调制稳频、调制光谱稳频、调制转移光谱稳频、双色激光稳频、频率电压转换稳频6种冷原子干涉实验中常用的稳频方法，分别阐述了各方法的原理、特点、适用领域，为半导体激光器的实际应用提供了参考。 |
| 英文摘要: |
| In cold atom interference experiments, the atoms need to be cooled and manipulated by laser, so the frequency stability of semiconductor lasers is required. Because of the large linewidth, poor power stability, slow drift and mode hopping, it is necessary to stabilize the frequency of semiconductor lasers. This paper introduces six common frequency stabilization methods in cold atom interference experiments, including saturated absorption spectrum stabilization, wavelength modulation frequency stabilization, modulation spectrum frequency stabilization, modulation transfer spectrum frequency stabilization, two-color laser frequency stabilization and frequency-voltage conversion frequency stabilization. The principles, characteristics and application fields of these methods are described respectively, which provide reference for the practical application of semiconductor lasers. |
