摘　　要：基于双程放大的基本原理,构建了一个双程脉冲激光放大器的实验模型,从脉冲激光双程放大速率方程组出发,建立双程脉冲放大理论模型,研究脉冲在双程放大系统中的传输特性,得到双程脉冲放大系统放大自发辐射能量与泵浦能量之间的关系、放大自发辐射能量与信号光重复频率之间的关系以及增益与输出信号光功率的关系。最后通过计算得到该放大系统模型的品质因数Q。Based on the principle of double-pass amplification, establishes a double-pass pulse amplifier experimental model. From pulse laser double-pass amplification rate equations, establishes a double-pass pulse amplification theoretical model, studies the transmission characteristics of the pulse in the double-pass amplification system, and obtains the relations between ASE （ amplified spontaneous emission ） and pump energy, the relations between ASE and the repeat frequency of the signal light, as well as the relations between the gain and the output signal power. Finally, the quality factor Q of the system is derived through calculating.
