摘　　要：采用求解Schr dinger方程和数值计算方法,研究了单模压缩真空场与运动Ξ型三能级原子相互作用过程中系统的动力学行为,讨论了系统参数对系统光场压缩效应的影响.数值计算结果表明:原子运动速度的大小决定了光场的压缩性质,当原子运动速度取较大值时,单模压缩真空场的初始压缩因子变化对光场的压缩性质产生明显影响.如选取适当的系统参数,就会产生完全压缩的光场.By means of solving Schroedinger equation and numerical calculations, the dynamic behavior of the interaction between the single mode squeezed vacuum field and a moving Ξ-type three-level atom has been studied, and the relations between the radiation squeezing effects and the coupling parameter of the system are discussed. The results of numerical calculations indicate that, the squeezed property of the radiation field is determined by the speed of the atom, and the squeezed property of the radiation field can be obviously influenced by the squeezing parameter of the system when the Ξ-type three-level atom moves with great speed, the radiation field can show complete squeezing effects when the system parameters are selected appropriately.
