摘　　要：运用全量子理论研究了三光子和单光子竞争模型中光子的反聚束效应,讨论了原子与双模光场相互作用的相对耦合强度以及光场的初始光子数对光场二阶相关函数的影响.结果表明:相对耦合强度和光场初始光子数的增加都可缩短光子反聚束效应的持续时间,光场初始光子数的增加可减弱光子的反聚束效应.The antibunching effects of the photon in the competing 3-and 1-photon transitions model are studied by means of quantum theory, and the influences of the relative competing strength between the atom and the two-mode field and the initial photon of the field on the second-order correlation function are discussed, It shows that the increase of the relative competing strength and the initial photon can lead to shortening the duration of antibunching effects of the photon, On the other hand, the hoton antibunehing effect decreases with the increase of the initial photon of the field.
