“神光Ⅱ”主放大器中的波形控制

CONTROL OF PULSE SHAPE IN “SHENGGUANG II” MAIN AMPLIFERS

理论分析了“神光Ⅱ”主放大器中影响增益饱和进而影响输出脉冲波形的各种因素 ,并用一套特征值数值模拟分析了各种因素对波形畸变程度影响的异同 ,提出了一种在调整脉冲波形的同时可在一定范围内连续调节输出能量的方案 .

Factors are analyzed theoretically which influence gain saturation and output pulse shape in 'SHENGGUANG II' main amplifier. Using a set of eigenvalues,we discuss the differences among the factors' influences upon the output pulse shape. A scheme is proposed to control output pulse shape,which could adjust the output energy continuously in some range at the same time.
