| 摘 要： | 本文给出了有初始相干性注入的V型无粒子数反转激光系统的非线性注解,分析了 系统参量变化对无粒子数反转激光增益和与探测场相互作用的两能级之间的粒子数差的影 响,我们发现伴随着驱动场Rabi频率的增加,粒子数差的变化表现出一个振荡行为,我们对这一新现象给出了解释。

| Abstract: | It is given the nonlinear solution of a V-type noninversion lasing system with coherence injected initially, analyzed the effects of varying parameters of the system on the gain without inversion and the population difference between the levels interacting with the probe field. We found that variation of the population difference shows a oscillation behavior with Rabi frequency of the driving field increasing and gave an explanation for this phenomenon. |
