摘　　要：本文研究了高Q腔中类Kerr介质和二能级原平同时与单模相干光场耦合作用时，类Kerr介质对光场量子相干特性的影响。结果表明：场态的演化依赖于类Kerr介质与光场的耦合强度，在一定时间场态演化呈现准可逆性。耦合强度愈大，相干态周期性再现愈显著。In this paper,the effect of Kerrlike medium on the quantum coherent propertiesof the light field are studied when single mode coherent state interacts with the two-levelatom inside a high-Q cavity filled with a Kerrlike medium.It is shown that the evolutionof the state of field depends on the coupling extent of the light field with the Kerr-likemedium, appearing to be quasi-reversible in definite time. The stronger the couplingextent, the more obvious the periodicty of the coherent state once more emerge.
