| 摘 要： | 利用J-C模型,在旋波近似下,给出了K模相干光场与二能级原子相互作用系统中系统态矢的演化。利用数值计算方法研究了三模相干光场与二能级原子相互作用系统中原子的偶极压缩效应,讨论了初始光场强度和光场相位对原子的偶极压缩效应的影响。结果表明:当初始光场较强时,原子只在演化的初期呈现短暂的间隙性压缩效应,光场相位决定原子的压缩方向,而光场强度变化对原子的偶极压缩效应影响很小。

| Abstract: | By means of the time-evolution operator method,the evolution of state vector in the system of a two-level atom interacting with k-mode radiation field is given.Using numerical calculation,atomic dipole squeezing in interaction of two-level atom with three-mode coherent state light field is studied.The influences the initial phase angle and intensity of initial coherent field on the atomic dipole squeezing are discussed.The results indicate that the atomic dipole squeezing has intermittence squeezing. |
