| 摘 要： | 应用全量子理论和数值分析的方法研究了在双模光场与运动的V型三能级原子相互作用过程中，原子运动对双模场压缩的影响。结果表明，当初始光场处于非关联双模相干态时，只有光场的第一正交分量被压缩，压缩程度随着原子运动与场模结构参数的增大而增大。另一方面，当初始光场处于双模压缩真空态时，主要是光场的第二正交分量被压缩，并且通过适当选择原子运动与场模结构参数，能够获得稳定的压缩光。

| Abstract: | The influences of atomic motion on squeezing of the double-mode field are investigated in the interaction with a moving V-type three level atom by means of the quantum theory and the method of numerical analysis. The results show, on the one hand, when the initial photon field is in non-correlative coherent state of double-mode, only the quadrature U1 is squeezed and the squeezed degree of U1 increases with the increasing of the parameter β which denotes the atomic motion and structure of the field mode. On the other hand, when the initial field is in the vacuum squeezed state of double-mode, the quadrature U2 is squeezed principally and we can obtain a steady squeezed light by choosing an appropriate parameter β. |
