  • 摘要: 基于GaAs场效应管电压控制电流和开关的特性,设计了一种任意电脉冲发生器,并成功应用于激光脉冲整形装置。该电脉冲发生器利用超宽带窄脉冲触发多个GaAs场效应管,产生多路负脉冲,通过模拟延时线依次将各路负脉冲延迟一定时间后经微带线耦合输出多路负脉冲叠加的波形;通过多路不同幅度的脉冲堆积效应来获得形状任意可调的整形电脉冲。为了满足惯性约束聚变(ICF)实验中对电脉冲幅度不能过小的要求,在电路的输出端接入增益可调的超宽带电压放大器,使脉冲幅度达到实验要求。利用设计的任意电脉冲发生器实现了脉冲幅度0~5 V可调、脉宽0~10 ns可调、时域调节精度为330 ps,整形方波脉冲下降沿为330 ps、上升沿为240 ps。实验结果表明,将产生的电脉冲注入光波导调制器,可获得理想形状的整形激光脉冲,提高激光脉冲的输出能量。
