【摘要】 研究了高Q腔内级联三能级原子与单模光场相互作用模型的腔场谱 .结果表明 ,原子初态处于上能级时 ,随R=g2 g1 的增大 ,真空场的拉比峰个数按 2→ 6→ 4→ 2→ 4的规律变化 ,在R 1时 ,所有的拉比峰都消失 .在初始场较弱时 ,腔场谱可出现 3峰、5峰或 7峰 .在初始场很强时 ,腔场谱中只有单一的经典共振峰 .如果原子初态处在中能级且R =1 ,腔场谱为简单的对称双峰结构 ,与标准J_C模型的谱相似更多还原

【Abstract】 The cavity field spectrum of a cascade three_level atom interacting with a single_mode field in an ideal cavity is investigated. When the atom is in the upper level and the field is vacuum initially,the number of Rabi peaks changes according to 2→6→4→2→4 with the increase of R=g 2/g 1, and all Rabi peaks disappear for R 1 Three_peak,five_peak or seven_peak structure appear for weak initial fields,and single resonance peak appears for a strong field. When the atom is in the middle level initially,the cavity field spectrum is of a two_peak structure with R =1 as the spectrum of Jaynes_Cummings model.更多还原
