级联三能级原子与相干态场相互作用过程中场的振幅N次方压缩

The Amplitude Nth-power Squeezing of Field in the Interactionof Coherent State with A Three-level Cascade Atom

本文研究了能级结构为级联型的三能级原子与相干态场相互作用过程中，光场的振幅N次方压缩特性，讨论了其压缩度随入射光场的初始平均光子数、原子与场的耦合常数和压缩阶数N的变化。

The propertics of the Nth-power squeezing of field in the interaction of coherentstate with a three-level cascade atom are investigated.The variations of the degree ofthe squeezing with the initial average photon numbers of the incident field,the couplingconstants of atom- field and the power N of squeezing are discussed.
