摘　　要：对激光抽运铯束管中Ramsey信号强度及线宽随微波功率的变化进行了数值计算,同时使用了-11~0 dBm范围内的微波功率进行了实验验证。结果表明,信号强度及线宽的计算值与实验值较为符合。当信号强度取最大值时,对应微波功率的计算值为-5.1 dBm,实测值约为-6 dBm;对于Ramsey线宽,最大计算值为562 Hz,对应的微波功率为-3.8 dBm,而实测最大值为552 Hz,对应的微波功率约为-3 dBm,两者基本相符,变化趋势也较为符合。The variations of Ramsey signal intensity and linewidth with microwave power in optical pumped cesium beam tube are numerically calculated,and then are experimental verified by the microwave power in the range of-11~0 dBm.The results show that the calculated signal intensity and line width are in good agreement with the experimental values.When the signal intensity is the maximum,the calculated value of the corresponding microwave power is-5.1 dBm,and the measured value is about-6 dBm;For Ramsey linewidth,the maximum calculated value is 562 Hz and the corresponding microwave power is-3.8 dBm,while the measured maximum value is 552 Hz and the corresponding microwave power is about-3 dBm.They are basically consistent with each other,and the change trends of them are also relatively consistent.
