摘　　要：导出了充满Ｋｅｒｒ介质的高Ｑ腔中非关联双模相干态场与Ｖ型三能原子相互作用系统的态矢量，通过数值计算，分析了Ｋｅｒｒ介质对原子能级布局概率的影响，绘出了原子布居概率的时间演化曲线，结果发现，原子布居概率受克尔效应的影响较大，随着克尔效应的增强在该曲线上附加一低频起伏．We derive the states vector of a V type three level atom interacting with uncorrelated two mode coherent states of arbitrary detunings in a cavity filled with Kerr like medium.It is shown by numerical calculation that the behavior of Rabi osillation is strongly affected by the Kerr medium.In addition,the Kerr medium caused a low frepuency fluctuation on the time evolution curve.We also discuss the influence of single photon detuning on the atomic level population.
