摘　　要：用时间演化算符方法研究了理想腔中近简Λ型三能级原子在微波驱动场作用下的发射谱。讨论了增大或减弱驱动微波场对原子发光谱的影响,及谱对Λ型三能级原子两个下能级裂距的依赖关系。The emission spectra of a nearly degenerate Λ-type three-level atom driven by a coherent microwave field in an ideal cavity are calculated by using the time-development operator method. The influence of enhancing and reducing the microwave field on the atomic emission spectra is investigated and the dependence of the spectra on the splitting of the two lower energy levels of the atom is explored.
