摘　　要：在假设原子初始处于激发态并计入原子-场耦合强度依赖性的条件下,用本征函数法研究了Λ型三能级原子与单模腔场共振相互作用系统的原子发射谱和腔场谱。结果表明,基态能级裂距对谱结构有重要影响。发射谱和腔场谱的谱线随初场增强不发生合并现象,腔场谱对初场光子统计性质不敏感。The eigenfunction method is adopted to investigate atomic emission and cavity field spectra in the system containing a A-type three-level atom resonantly interacting with a single-mode field. The atom is assumed initially in the upper atomic state and intensity-dependent coupling is taken into account. It is found that the splitting between the lower levels has a great influence on the spectral structure for both the emission spectrum and the cavity field spectrum. Combination of spectral lines does not take place with increasing intensity of the initial field and the cavity spectrum is not sensitive to the statistics of the initial field.
