摘　　要：分别研究了初始处于基态或激发态的一个二能级原子与相干态光场相互耦合的双光子Jaynes-Cummings模型中场的振幅N次方压缩特性,并讨论了其压缩度随入射光场的初始平均光子数和压缩阶数N的变化.In this paper, the properties of the Nth-power squeezing of field in the two-photon Jaynes-Cummings model of an atom initially in the ground or existed states coupling with the coherent state are investigated, respectively. The variations of the degree of the squeezing with the initial average photon numbers of field and the power N of the squeezing are discussed.
