摘　　要：研究了充满Kerr介质的高Q腔中二能级原子和双光子Jaynes-Cummings模型腔场谱。给出了初始光场为光子数态时的计算结果,讨论了相位自调制效应对腔场谱结构的影响。发现随一模相位自调制效应的逐渐增强,本模双峰频差劈裂增加,两模峰高受到有限调制,使各模低频峰高度渐增而达到饱和,高频峰高度渐减直至消失,由非对称的双峰结构渐变为单峰结构。The cavity field spectra for the nondegenerate two-photon Jayners-Cummings model with an additional Kerr-like medium were investigated. The results of the initial fields in pure number states were presented, and effects of self-phase modulation on the spectra structure were analyzed. It is found that the cavity field spectra are generally in two-peak structure for each mode. With the increase of the self-phase modulation effect of one mode, the peak-space of this mode get a raise and one peak rises and the other peak reduces for the both mode spectrum.
