Kerr介质中非关联双模相干态光场与V型三能级原子的相互作用

Interaction of Two mode Initially in Uncorrelated Coherent States with the V type Three level Atom in a Kerr like Medium

导出了充满Ｋｅｒｒ介质的高Ｑ腔中非关联双模相干态光场与Ｖ型三能级原子相互作用系统的态矢量，通过数值计算，分析了光与原子之间单光子失谐量和Ｋｅｒｒ介质对原子能级布居概率及光的量子统计特性的影响，给出了原子布居概率和双模场量子统计特性的时间演化曲线。结果表明，原子布居概率受Ｋｅｒｒ效应的影响较大，且在该曲线上附加一低频起伏。通过对双模光场二阶相干度的分析：一模呈现亚泊松分布；另一模呈现超泊松分布。

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 frequency fluctuation on the time evolution curve. The quantum statistic properties of two mode field also is investigated, one mode shows sub Poissonian photon disrbution, another super Poissonian.
