基于相干布局囚禁（CPT）原子钟系统体积小的要求,设计加工了300μm厚的薄铷原子汽室.本文采用薄原子汽室,利用饱和吸收稳频方法实现了对激光器的频率锁定.闭环后激光器的频率稳定度在100s内为10-12量级,完全可以满足CPT原子钟对光源的要求.

Based on the small size requirements of CPT atomic clock system,we design and process of the thin Rb atomic vapor cell with 300μm.This paper uses thin atomic vapor cell and saturated absorption frequency stabilization method to achieve the laser frequency locking.After the locking circuit operating,the frequency stability of the laser reach a minimum of 10-12 for an averaging time of 200s and can meet completely the requirements of CPT atomic clock on the light source.
