摘　　要：研究了含Kerr介质腔中耦合双原子与辐射场相互作用模型的腔场谱,给出了初始时刻原子处于激发态、光场处于光子数态时的计算结果,讨论了Kerr效应对谱结构的影响。结果发现,随Kerr效应增强,各峰频率不断升高;Rabi峰一般为4峰结构,其中2峰强度逐渐减弱直至消失,另2峰在χ/g=0.7附近有唯一极大值点,腔场谱演化为双峰结构,其频差不断增大;当n>0时,只有1峰强度单调升高直至饱和,其余各峰强度均单调减弱直至消失,腔场谱最终演化为高频的单峰结构。The cavity field spectra of two coupling atom Jaynes-Cummings (J-C) model with Kerr-like medium were studied. The calculation results for the initial fields in pure number state and the atom in the upper level were presented. Effects of Kerr medium on the spectral structure were discussed, it is found that every peak frequency get a rise with the increase of the Kerr-effect. Four Rabi peaks appear when the field is vacuum. Two Rabi peaks become weaker until disappearing with x/g increase. The other two peaks get the highest at x/g 0.7 and the peak-space increases gently. When n > 0, only one peak rises to the highest point, the others reduce until disappearing. The cavity field spectra become single-peak structure.
