| 摘 要： | 精确求解了双模压缩真空场与Ｎ型四能级原子双光子跃迁相互作用系统的波函数，并讨论了系统中光场的压缩效应及光子的统计性质．数值计算结果表明，光场的两个正交分量的均方涨落均呈现周期性的压缩，其压缩程度与系统的初始状态有关；光场光子的统计性质也依赖于系统的初始状态，光场两模之间的相关是一种非经典相关．

| Abstract: | The wave-function of the system of two-mode squeezed vacuum field interacting with N-type four-level atom is solved exactly, and tile quantum properties of the light in the system are studied by means of numerical method. The results of the studies indicate that the fluctuations of two quadrature components of light can be squeezed periodically, and this squeezability is related to the initial state of the system. The statistic properties of the photon depend on the initial state of the system, and the correlation of the two mode of light is non-classical. |
