开放的V型单色非相干泵浦系统的非线性理论

本文给出了具有单色非相干泵浦场的开放Ｖ型系统频率上转换无粒子数反转激光的非线性理论，研究了驱动场的Ｒａｂｉ频率、原子注入速率、原子退出速率、能级间衰变率及非相干泵浦速率对系统无粒子数反转激光的增益、色散以及布居数差的影响，讨论了无粒子数反转激光增益的稳定性。

Nonlinear Theory of an Open V-type System with a monochromatic Incoherent Pump

We gave the nonlinear theory of invers ionless lasing of frequency up-conversion in an open V-type system with a mon o chromatic incoherent pump.We studied the effects of the Rabi frequencies of the driving fields,the injection rates,the exit rate,the decay rates between atomic levels,as well as incoherent pump rate on the gain without inversion,dispersion and the population difference of the system,and discussed the stability of the g ain without inversion.
