摘要
相干态和压缩相干态是量子光学研究中的两种典型光场量子态,它们的相位分布规律可表征光场的相干性演化.主要研究腔体存在耗散的情形下这两种相干态的相位分布概率,通过P-B相位理论得到相位分布的解析计算结果,对该结果进行数值分析后发现,两种相干态光场的相位分布概率在不同光子数、腔场耗散系数时,会表现出一些特殊的相位演化规律.
The coherent state and the squeezed coherent state are two typical optical field quantum states in the research of quantum optics.Their phase distribution can indicate the coherent evolution of the optical field.In this paper,the phase distribution probability of these two coherent States is studied by using P-B phase theory.After numerical analysis of the analytical results,it is found that the two coherent light fields exhibit some special quantum characteristics when the number of photons and the coefficient of cavity field dissipation are different.
