用于激光脉冲整形的任意电脉冲产生技术研究
Research on Arbitrary Electrical Pulse Generation Technology for Laser Pulse Shaping*
摘要
为了实现整形脉冲调节的智能化，用计算机分别控制多个GaAs场效应管栅极偏压，并对场效应管产生的脉冲进行脉冲叠加，以控制整形电脉冲的形状；为提高输出整形脉冲的稳定性并减小触发晃动时间，优化设计了脉冲整形电路，结果表明：脉冲输出幅度1～5 V可调；方波脉冲输出宽度0～3 ns；脉冲前后沿分别为250 ps和350 ps；幅度稳定性：～4%（峰峰值) ；时域调整精度200 ps.
Abstract
To realize intelligently adjustable pulse-shaping, a computer was used to control the gate bias of each GaAs filed-effect transistor (FET) and superpose pulses generated by them. To improve the stability and reduce the trigger jitter of shaped-pulse, the pulse shaping circuit was properly designed. 1~5 V adjustable amplitude, 0~3 ns square wave width, rising edge 250 ps falling edge 350 ps, 4% (peak to peak) amplitude stability, and 200 ps time domain adjustment precision were obtained.
