【摘要】：通过建立被动型CPT铯原子钟的理论模型,开展CPT信号与铯原子气室特性参量间关系的仿真分析和研究,建立铯原子气室设计及分析方法,得到了被动型CPT铯原子钟最佳设计参数,直径10mm、长度10mm、缓冲气体为N2的圆柱形铯原子气室,最佳工作参数为:工作温度为320K、气体压强值50Torr。并经多波长多普勒吸收光谱、CPT信号锁定及频率稳定度测试等实验,验证了理论模型的正确性,为开展高性能芯片级CPT铯原子钟的设计、参数优化提供了一种研究方法。
[Abstract]:By establishing the theoretical model of passive CPT cesium atomic clock, the simulation analysis and study of the relationship between CPT signal and the characteristic parameters of cesium atomic gas chamber are carried out, and the design and analysis method of cesium atomic gas chamber is established. The optimum design parameters of passive CPT cesium atomic clock are obtained, which are 10mm in diameter, 10mm in length and N2 in buffer gas. The optimum working parameters are as follows: the working temperature is 320K, the gas pressure is 50 Torr. The theoretical model is verified by the experiments of multi-wavelength Doppler absorption spectrum locked signal and frequency stability test, which provides a research method for the design and parameter optimization of CPT cesium atomic clock with high performance.
