摘　　要：从半经典理论的麦克斯韦－布洛赫方程出发，对种子激光脉冲在再生和多程放大器中的放大过程进行了分析，结合实际的物理条件得出了放大器的峰值输出的解析表达式，并详细地分析了放大器的损耗和增益对峰值输出的提高和稳定的影响．得出了一些对实际搭建工作具有指导意义的结论．Based on the semi classical theory and Maxwell Bloch equations, the amplification of the seed pulse in the laser regenerative and multi pass amplifiers is analyzed. The analytical expression of the peak fluence is obtained by assuming some actual physical conditions. A relationship between the enhancement and stability of the peak output and the gain, loss of the amplifier is discussed in detail. The results are instructive to the actual establishment.
