kerr介质中级联三能级原子与光场非共振相互作用过程中原子的动力学特性

Dynamical Properties of a Three Level Cascade Atom Interacting Non resonantly with Optical Field In a kerr Medium

本文导出了充满ｋｅｒ介质的高Ｑ腔中级联型三能级原子与双模ＳＵ（１，１）相干态场非共振相互作用系统的态矢量，并以此计算三能级原子布居概率随时间的演化，数值计算显示，ｋｅｒ效应产生与两能级原子不同的Ｒａｂｉ振荡特征，而ｋｅｒ效应与失谐的共同作用导致出现电子绝热跃迁转移现象。

We first derive the state vestor of a three level cascaed atom interacting Non resonantly with two mode SU(1,) cohevent states in a kerr like medium.It is showed by numerical calculations that the kerr effect results in different charaters of the Rabi oscillation,as compared with the two level atom case,While adiabafic frousision fransfer phenomanon of elecfron is found to be due to kerr effect and defuning.
