简并量子拍频激光器等效两能级模型理论

Equivalent Two-level Model Theory of the DegenerateQuantum-beat Laser

本文运用缀饰原子方法，得到了在一定条件下被微波场驱动的Λ－型简并量子拍频三能级系统等效于两能级系统的结果，利用两能级系统的激光器理论很便利地给出简并量子拍频激光器的运动主方程。

The dressed-atom approach is used to present the type three-level sys-tem driven by a microwave field is equivalent to a two-level one. The master equationof the single-mode field of the degenerate quantumbeat laser can be obtained muchexactly conveniently by using the theory of the two-level system laser.
