In chapter 2 , we analyzed the effect of the driving field phase fluctuation on the gain and dispersion and population differences in an open v - type three - level non - inversion lasing system and then discussed the effects of the incoherent pumping rate , the ratio of the atomic injection rates , the atomic exit rate , the rabi frequency of the probe and driving fields and their corresponding detuning on the gain , dispersion and population differences of the system , and got some important conclusions different from those in closed or other open systems 第二章讨论了驱动场的相位涨落对开放的v型三能级无反转激光系统的影响，根据解析解的数值计算结果讨论了非相干泵浦速率、粒子注入速率之比、粒子退出速率、探测场和驱动场的rabi频率和相应失谐对系统增益、色散和粒子数差的影响，得到了一些不同于封闭的v型系统及其他开放的无反转激光系统的重要结论。
