摘　　要：研究了原子与双模光场非简并拉曼耦合过程中交流斯塔克位移对腔场谱的影响 .给出了原子处于基态且双模初始场为光子数态、相干态和压缩真空态时光谱结构的数值结果 .发现数态光场在弱场条件下每模腔场谱都是三峰结构 ,在强场条件下则为双峰或单峰结构 ,相干态和压缩真空态光场的腔场谱在弱场或强场条件下都是双峰结构 .随着斯塔克位移参数的变化 。The cavity field spectrum of an atom interacting with two-mode field through non-degenerate Raman coupling with the presence of AC-Stark shift in an ideal cavity is investigated. The results for the atom in the low-level state and the initial fields in pure number states, coherent states, and squeezed vacuum states are calculated. When the initial fields are in number states, the three-peak structure of each model cavity field spectra appear for weak fields, and two-peak or single-peak structure appear for strong fields. When both field modes are in a superposition of number states initially, the cavity field spectra are generally of two-peak structure. With the increase of γ=g 2/g 1,one peak rises and the other peak reduces.
