| 摘 要： | 导出了类Kerr介质中双模SU(1，1)相干态场与四能级原子相互作用系统的态函数，研究了Kerr效应和初始光场强度对双模SU(1，1)相干态场的互关联函数、Cauchy—Schwartz不等式及二阶相干度的影响。结果表明：Kerr效应对两模间的相关性、相关程度以及光子的聚束与反聚束效应的影响与初始光场明显相关。

| Abstract: | The state function of the two-mode SU(1,1) coherent states field interacting with four-level atom added Kerr-like medium was derived. By using the state function it was studied that the influence of the Kerr effect and the initial light field intensity on the two-mode intensity correlation function, the Cauchy-Schwartz inequality, and the second-order correlation function for each mode. The results indicate that the influences of Kerr effects on the properties of the correlation on the correlation intensity between the two-mode on the bunching or antibunching effect of the two-mode SU(1,1) coherent states are obviously related to the initial intensity of the light field. |
