摘要
本文采用数值计算方法研究了强场作用下二能级原子双光子过程中辐射场的压缩效应．结果表明：辐射场主要处于压缩态，并周期性地出现短时的非压缩效应，随着值的不断增大，场与原子的非线性耦合越来越强，压缩的最大深度不断加深．
In this paper,the squeezing properties of the radiation field in the two-photon process under strong coherent field of initial state are studied by numerical calculation. The results show that the radiation field is mainly in squeezed states,and the short-time non-squeezing effects of the radiation field appear periodically; with the increasing of the value of,the nonlinear coupling between the field and the atom is getting stronger and stronger,and the maximum intensity of squeezing is increasing gradually.
