Measurements and Analyses of Light Frequency Shift in a Small Optically Pumped Cesium Beam Frequency Standard

在弥漫激光场抽运斜入射光检测小型铯原子束频标实验系统上，对弥漫激光场产生的散射光所引起的光频移(主要是交流斯塔克移动)以及光抽运区产生的荧光引起的光频移对铯束频标准确度的影响作了仔细的实验测量，并与理论计算结果作了比较分析。测量结果表明在正常工作条件下，散射光引起的光频移小于-2×10-13，荧光引起的光频移值在0.8×10-13左右，这样的光频移对小型光抽运铯束频标来说是可以接受的。In the experimental system of diffused laser light field pumped sharp angle incidence laser light probing small cesium beam frequency standard, the light frequency shift (mainly the AC Stark shift) caused by diffused laser light comes from the diffused laser light field, and the light frequency shift caused by fluorescent light comes from the pumping region have been measured carefully. The measured results were analyzed and compared with the calculated results. The results proved that, under normal working conditionin, the light frequency shift caused by diffused laser light is less than -2×10-13, the light frequency shift caused by fluorescent light is about 0.8×10-13, such results are acceptable for a small optically pumped cesium beam frequency standard.高等院校骨干教师基金; 国家自然科学基金中文核心期刊要目总览(PKU)中国科学引文数据库(CSCD)02129-1332
