Light Frequency Shift in a Cesium Beam Frequency Standard with Sharp Angle Incident Laser Light Pumping

本文对斜入射激光抽运斜入射激光检测小型铯原子钟实验系统上光抽运区荧光引起的光频移 (主要是交流斯塔克移动 )作了理论计算。结果表明斜光抽运方案可以有效降低铯原子束频标中的光频移。

In the experimental system of the small cesium beam frequency standard with sharp angle incident laser light pumping and sharp angle incident laser light probing, the light frequency shift (mainly caused by AC Stark effect) caused by fluorescence from pumping region was calculated theoretically. The results show that the light frequency shift can be effectively reduced in the sharp angle laser light pumping scheme. In addition, a new method to measure the light frequency shift by changing the diffusing angle of the pumping laser light beam was presented.
