Optimum Design of Fluence Spatial Distribution for a Multipass Amplifier

由包含弛豫作用的速率方程出发，建立了关于放大器能流密度空间分布最优问题的数学模型。采用最优问题求解方法，计算得到了多程放大器光束空间分布的优化设计，并分析了由此引起的对于放大器总体性能的影响。

Based upon the laser rate equations including relaxation between energy levels, the optimum model of a multipass amplifier is constructed. By computer simulation, an optimum input fluence distribution is obtained and the performance of the laser amplifier under such optimum is discussed.
