摘　　要：研究了封闭的Ｖ型三能级激光系统。该系统利用外加双色泵浦场通过Ｒａｍａｎ过程耦合两个高能级来建立原子相干．激光跃迁发生在一个高能级与低能级之间．结果表明该系统可以建立裸态无反转激光，其增益来源于缀饰态原子相干。In this paper; a closed V-type three-level system is studied. In the system;atomic coherence is induced by a Raman process of coupling the two upper levels; and lasingoccurs at the transition between either of the upper levels and the ]ower level.It is shownthat this system can exhibit lasing without inversion in the bare state;and the gain arisesfrom the atomic coherence in the dressed state.
