| 摘 要： | 介绍基于85Rb原子相干布居囚禁(CPT)现象的微型原子钟的设计与实现，系统以MSP430单片机作为主控芯片，实现电流源、TCXO和射频等功能模块，并与CPT原子钟物理部分实现联调与整机封装，实现了高稳定度、低功耗的小型CPT原子钟。整机体积只有31 cm3，功耗为660 mW，测得10 MHz输出信号稳定度约为2×10-10 s-1,4×10-11/1 000 s。系统采用全宽调制在85Rb的D1线实现CPT原子钟方案，可提升CPT共振谱线对比度，提高原子钟稳定度。

| Abstract: | A Coherent Population Trapping(CPT) atomic clock servo control circuit is designed based on the CPT phenomenon of 85Rb. Taking MSP430 chip as a platform, combining with the physical device made up of Vecsel laser, photoelectric detector, and small 85Rb vapor cell, a miniature atomic clock with the high-performance, high stability, low power consumption and small size is implemented. The volume is 31 cm3 and the power consumption is 660 mW. The frequency stability of 10 MHz measured is 2×10-10/s, 4×10-11/1 000 s. Full-hyperfine-splitting frequency modulation is used to improve the frequency stability. |
