When decay rate in the coupling channel is greater than that in the probe channel, the incoherent population pumping in the probe channel can create the gain without inversion.
当耦合路径上的衰变率大于探测路径上的衰变率时，探测路径上的抽运导致了非逆转增益现象的产生。
Using rate equation theory, the equation group including the population inversion density of the gain medium, photon density and the absorber ground state population density is acquired.
利用速率方程理论，得到包含激光增益介质反转密度、光子密度和饱和吸收介质基态布居数密度的速率方程组。
