给出了在开放的V型三能级系统中的无粒子数反转激光理论。定态增益分析表明,在一定的条件下,无粒子数反转激光能够实现而不需要一个附加的泵浦场存在, 而这个泵浦场在一个普通的封闭V型三能级系统中实现无粒子数反转激光是必不可少的。图示并分析了系统增益对驱动场和其他参量的依赖性。

A Theory of noninversion lasing in an open V-type three-level system is presented. The steady-state analysis shows that under certain conditions, noninversion lasing can be realized without an additional pump which is required by noninversion lasing in a general closed V-type three-level system. The dependence of the gain behavior of the system on Rabi frequency of the driving field and other parameters is also illustrated and analyzed.
