摘　　要：采用全量子理论和数值计算方法讨论了耦合双原子和单模光场相互作用中辐射光场光子数分布的演化特性,结果显示:通过光场和耦合双原子的相互作用,使得不具有反聚束效应和光子亚泊松分布的单模光场获得了非经典特性,并且随着耦合强度的增大,非经典性增强,说明通过适当的方法可以制备非经典辐射光场.The evolution features of the photon number distribution in which the coupled two - level atoms interact with single -mode light field by full quantum theory and numerical calculation method. Results show that ： through the interaction of the light field and coupled two - level atoms, single mode light field which doesn＇ t have bunching effect and sub - Poisson distribution gains the non - classic features, and with the increase of coupling strength, the non - classic features enhance. It proves the non - classic radiation field is prepared with the adequate methods.
