摘要
详细分析了弛豫作用在高功率激光器中对反转粒子数的影响，在经典速率方程理论的基础上，推导了包含弛豫作用的一般性速率方程，讨论了弛豫效应与放大器总体性能之间的关系，并给出具体放大器的计算实例。
The relaxation between laser levels can strongly affect the operation and efficiency
of high power laser amplifier. The influence of the thermalization rates among the components
of the two multiplets to which the laser level belong and depletion rate of terminal laser level is
studied in detail. A group of modified laser rate equations in consideration of the influence of
thermalization and depletion between laser levels is are obtained. The properties of a practical
amplifier is presented by numerical simulation.
