摘　　要：详细介绍了高压电平及台阶宽度可调的三台阶快脉冲产生的技术方案，实现了快脉冲的台阶电平200～700 V范围内可调，台阶宽度100 μs 范围内可调。实验结果表明该技术方案能输出满意的脉冲波形。以此台阶脉冲信号为单纵模激光器提供驱动，调节三台阶快脉冲的幅度和持续时间，单纵模激光器可以获得平滑稳定、低抖动的输出波形。该技术可应用于高功率固体激光驱动器以及其他需要多台阶高压可调快脉冲发生器的设计中。The technology for high voltage level and three- pedestal width- adjustable fast pulse generation is revealed in this paper. The voltage level can be adjustable from 200 to 700 V, and the width of pedestal can be adjusted within 100 μs . This technology is already applied in the experiments and the experimental results match the expectations. Single longitudinal mode laser powered by this adjustable three- pedestal pulse can be smooth and stable. This technology can be used during the design of high power laser facility and other equipments with multi-pedestal high voltage fast pulse generator.
