摘　　要：研究了在充满Kerr介质的高Q腔中两个具有偶极-偶极相互作用的二能级原子辐射谱,给出了初始光场为Fock态和相干态时辐射谱的数值结果。讨论了Kerr效应对谱结构的影响。在初始注入光场为较强的相干态时,辐射谱除中心单峰外,两侧各出现一个多峰梳状边带,峰的个数随初始场平均光子数n的增大而增多,峰间距随Kerr介质与光场的耦合系数x的增大而增大,两个边带则随xn的增大逐渐远离。The emission spectra of two coupling atoms in a high Q cavity with an additional Kerr medium are investigated. The results for the initial fields in pure number states or coherent states are presented. The effects of Kerr medium on the emission spectra are analyzed. When the inject field is in a coherent state with large average photon number n , single high peak at center and two multi-peak sidebands like comb spectrum appear. The peak-number of the sidebands increases along with accretion of n . The peak-space increases along with accretion of Kerr effect. The two sidebands will leave away due to the increase of the average photon number or the Kerr effect.
