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

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.

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

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.
