摘　　要：研究了在充满Kerr介质的高Q腔中V型三能级原子与压缩相干态光场相互作用系统Mandel因子Q(t)的时间演化规律;讨论了Kerr介质强度系数μ、光场压缩因子γ、光场相干振幅分量模平方|α|2和原子-场的耦合系数λ对光子统计分布特性的影响。结果发现:μ、γ、|α|2和λ都影响了Mandel因子Q(t)演化曲线量子崩塌-复苏效应的周期性,同时,也影响了受激辐射场的光子统计分布的状态和特性。The evolution properties of Mandel Q(t) with time in the system of V-type atom interacting with squeezed coherent light field inside a high Q with a Kerr medium was investigated. It was shown that the intensity coefficient μ of Kerr medium, the squeezed light field factor γ, the coherent vibration amplitude |α|2 of the light field and the coupling parameter A of the field-atom influence the quantum collapse-revival periodicity of the evolution curves of Mandel factor Q(t). Meanwhile, they all influence the states and properties of the photon statistical distribution of radiation field.
