介绍了高功率固体激光驱动器中单通片状放大器 (SSA)的模拟和实验研究结果。对放大器能量传输的各环节进行全系统模拟 ,在能源系统优化的前提下 ,对不同抽运条件和不同抽运腔构型放大器的增益特性进行实验研究 ,2 2kV工作电压下 ,获得了 4 9%cm-1的小信号增益系数和 2 4 3%的储能效率。同时还分析了放大器的抽运热畸变及波前变化 ,实验测量了由抽运引起的腔内洁净度变化情况。 The simulation and experimental results of single chip amplifier (SSA) in high power solid state laser driver are introduced. The whole process of the energy transfer of the amplifier was simulated. Under the premise of the energy system optimization, the gain characteristics of amplifiers with different pumping conditions and different pumping cavity configurations were experimentally studied. Under the 2 kV working voltage, the gain of 49 Small signal gain coefficient of% cm-1 and energy efficiency of 24.3%. At the same time, the pump thermal distortion and wavefront change were also analyzed, and the change of cavity cleanliness caused by pumping was measured experimentally.
