摘要
研究类克尔介质中非旋波近似下三能级原子与场相互作用系统的原子占居态几率的时间演化；讨论了光场频率ω及类克尔介质常量ｘ 对原子占居态几率的影响． 结果表明：虚光场的作用使原子占居态几率的时间演化曲线中出现量子噪音，而Ｋｅｒｒ 介质效应会抑制量子噪音的产生；原子吸收率随ｘ 的增大而降低；系统的粒子数反转随ｘ 的增大明显减弱，但随ω的增大有所增强．
In this paper,the evolution of atomic level occupation probability of a three level atom interacting with cavity field filled with Kerr medium using C RAW is studied.The effect of field frequency ω and Kerr parameters x on atomic level occupation probability is investigated.The results show:the quantum noise which is caused by the virtual photon field becomes weak when x increases;The absorbability of atom decreases when x increases,but it increases when ω increases.
