摘　　要：本文研究了一个位于高QKerr介质腔中初始时处于基态的级联三能级原子与双筷SU（1，1）相干态场相互作用系统中，Kerr效应对原子动力学行为和光场性质的影响.结果表明:随着Kerr效应增强，拉比振荡的回复周期缩短，双筷光场的压缩量总是减小，两模间的关联程度减弱，但非经典相关程度则存在增强的情形。We have studied the influence of the Kerr effect on the atomic dynamic behaviorand the properties of light field in the system of double SU(1,1) coherent state interactingwith a three-level cascade atom initially in a ground state inside a high Q cavity filledwith a Kerr medium.We have shown that with increasing Kerr effect, the revival periodof the Rabi oscillation becomes smaller; the quantity of two-mode squeezing is alwaysdecreasing;intermode correlation becomes greater;but nonclassical correlation may increasein some conditions.
