【摘要】 本文运用缀饰原子（ｄｒｅｓｓｅｄ－ａｔｏｍ）方法，得到了在一定条件下被微波场驱动的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。更多还原

【Abstract】 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.更多还原
