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100μs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 technical scheme of generating three fast pulses with high voltage level and adjustable step width is introduced in detail. The fast pulse step level is adjustable in the range of 200-700 V and the step width is adjustable in the range of 100 μs. Experimental results show that this scheme can output a satisfactory pulse waveform. The step pulse signal is used to drive a single longitudinal mode laser to adjust the amplitude and the duration of three step fast pulses. The single longitudinal mode laser can obtain a smooth, stable and low jitter output waveform. The technology can be applied to high-power solid-state laser drivers and other designs that require multi-stage, high-voltage, tunable fast pulse generators.
