摘　　要：研究了V-型量子拍频三能级原子与单模压缩真空场作用过程中系统的动力学行为,运用数值方法讨论了系统参数对系统光场压缩特性的影响。研究表明:单模压缩真空场的初始压缩因子和V-型三能级原子的相对失谐量的大小对系统光场的压缩特性有很大的影响,通过选择合适的系统参数,光场可以被完全压缩。The dynamic behavior of the interaction between the V-type quantum-beat three-level atomic system and the single-mode squeezed vacuum field has been studied based on the quantum theory. By using the numerical method, the relations between the quantum properties of the light and the coupling parameter of the system are discussed. The results indicate that the squeezed property of the light is dependent on the squeezing parameter of the squeezed vacuum field and the detuning of the V-type three-level atoms. The radiation field can be completely squeezed through choosing optimal parameters of the system.
