• In section one , we analyze the mechanism of lwi gain , and study the effects of the rabi frequency q of the driving field , the injection rates ratio rb / r ~ , the exit rate r0 , the decay rates ~ and rab between atomic levels , as well as 3 incoherent pump rate r on the gain without inversion , dispersion and population difference of the system . in section two , we discuss the effects of the detuning of the driving field and the probe field on the gain
  在第一节中分析了无粒子数反转激光增益产生的机制、研究了驱动场的rabi频率、粒子注入速率比值r _ b / r _ c 、粒子退出速率r _ o 、能级间的自发衰减速率r _ ( c - b ) 、 r _ ( a - b )和非相干泵浦速率r对增益、色散和粒子数差的影响；第二节讨论了驱动场和探测场的失谐对无粒子数反转激光增益的影响。
