利用全量子理论,研究了在Kerr介质中,耦合二能级双原子与单模光场相互作用过程的反聚束效应,着重讨论了Kerr介质对场的二阶相干度的影响,并揭示了初始场强及原子间耦合系数的变化与场的二阶相干度的关系.

In this paper, the antibunching effect of two coupling atoms interacting with a single mode light field in a Kerr medium is studied by means of the quantum theory. The influences of the Kerr medium on the degree of second order coherence is also discussed. The relations between the excited field intensity, the coupling constants of two atoms and the degree of second order coherence are revealed.
