摘要 研究了Kerr效应对单个二能级原子与二项式光场相互作用系统腔场谱的影响.研究发现,腔场谱结构对Kerr效应非常敏感,Kerr效应的轻微改变可使腔场谱结构明显变化,谱线劈裂、右移、间距增大、失去原有的对称性.在Kerr效应一定的情况下,一模腔场谱对另一模腔场的强弱也很敏感,一模腔场谱的增强可使另一模腔场谱线劈裂、右移、间距渐大,形成中心峰强,边峰弱,不对称的梳状结构. The cavity field spectrum of the nondegenerate two-photon Jayners-Cummings model with an additional Kerr medium is studied. The results for the initial fields in binomial states are presented. It is found that the Kerr medium affected the structure of the spectrum sensitively. When the Kerr-effect en- hanced, the distance and number of the peaks are both increase; meanwhile every peak frequency get a rise. The spectrum structure of one mode is affected by the intensity of the other mode. Under the condition of strong initial fields, the complicated multi-peak structure like an arched comb appears for each mode.
