估计了光引起的频移，即光抽运Cs光束频率标准中的光移。通过沿Cs光束引入激光来测量单片光引起的频移。位移对激光频率的相对依赖性与理论很好地吻合，但绝对位移是理论的一到两倍。标准中光抽运和光检测引起的光移估计分别小于2*10/sup -15/和1*10/sup -16/，在目前的发展状态下都可以忽略不计。>
Frequency shifts caused by light, which are called light shifts in an optically pumped Cs beam frequency standard, were estimated. Frequency shifts due to monolithic light were measured by introducing laser light along the Cs beam. The relative dependence of the shift on the laser frequency agreed very well with the theory, but the absolute shift was between one and two times that of the theory. The light shifts due to the optical pumping and optical detection in the standard are estimated to be less than 2*10/sup -15/ and 1*10/sup -16/, respectively, and both are negligible at the present state of development. >
