摘　　要：研究Kerr介质中 ,非旋波近似下 ,一个级联型三能级原子与光场相互作用的二阶相干度的时间演化 ,讨论了Kerr效应和虚光场效应对场的光子反聚束效应的影响 .结果表明 ,虚光场的影响使系统出现量子噪声 ;而Kerr介质常量x、共振频率ω的增大及原子 场耦合系数 g的减小都将降低原子对激发场的吸收效率 ,削弱受激辐射场的光子反聚束效应 。We have studied the interaction between a cascacle three\|level atom and the cavity field filled with Kerr medium by C\|RWA. The influence of Kerr effect and virtual photon field on the photon anti\|bunching is discussed. The results show that the quantum noise appears under C\|RWA; the increase of x and ω or the decrease of g leads to the decrease of absorbance of atom and the reduction of photon antibunching;especially,the interaction is influenced obviouslly by g .
