简并量子拍频三能级单原子的辐射谱

Emission Spectrum of a Λ type Degenerate Quantum beat three level Atom

采用时间演化算符方法，研究腔内单模光场中被相干微波场驱动的Λ型简并量子拍频三能级单原子的辐射谱，给出了辐射光谱公式．在初始光场为粒子数态光场激励下，辐射谱一般为对称的六峰结构，各峰值频率与作用光场的光子数有关，而强度与驱动微波场相关；

A study is conducted on the emission spectrum resulting from the interaction between a single mode field and a Λ type degenerate quantum beat three level cavity bound atom driven by a microwave field by means of a time evolution operator. The physical spectrum expression of radiation emitted by the atom is given out. For the initial field in pure number states, the spectrum shows the symmetrical six peak structure related the driving microwave. Also, a discussion is offered of the relationship between the emission spectrum and atom field coupling constants.
