采用求解Schr(o)dinger方程和数值计算方法,研究了Kerr介质中双模奇偶纠缠相干光场与V型三能级原子相互作用系统的光子统计性质,分析了双模奇偶纠缠相干光场的纠缠度、Kerr介质与光场的耦合强度、双模光的平均光子数、失谐量和原子基态概率幅对光子统计性质的影响.结果表明:双模奇偶纠缠相干光场的纠缠程度对光子统计性质的影响不十分明显;Kerr效应增强使演化曲线上下移动,曲线的振荡频率变大、振荡幅度变小;保持场模1的光子数不变而改变场模2的光子数,会使演化曲线向上或向下显著移动、曲线的振荡幅度发生变化;失谐量的改变对光子统计特性也有一定影响;原子初态中基态概率幅的变化使演化曲线上下显著移动.
