摘　　要：介绍了光抽运铯束管的光频移测量的原理和结果，并对结果进行了简要的分析，估算了射入Ramsey腔的相应光强。产生散射光光频移的原因是抽运光和检测光通过漫反射进入微波腔的漂移区与铯原子相互作用所致。In this paper the light frequency shift of an optically pumped Cs beam frequency standard is reported and analyzed. The cause for the stay light frequency shift is discussed： interaction between the stay light coming from pumping and detecting laser and atom in the microwave cavity.
