摘　　要：一种新型的由电压充电传输线(VCTL)及本征硅光电导开关组成的极快电脉冲发生器巳研制成功。采用波长为1.06μm、脉宽为80ps的激光脉冲激励环形电路中的开关,可以获得具有极快上升下降沿(小于200ps)、宽度决定于环形线长、开关效率决定于负载的纳秒方波脉冲。A novel ultrafast electronic pulse generator system consisting of a voltage charged transmission line(VCTL) and an intrinsic silicon optoelectronic switch has baon successfully developed. The switch in the circular circuit is illuminated by a laser pulse at 1.06 micrometers wavelength and 80 picoseconds width. A nanosecond square-wave electronic pulse with an ultrafast risetime and falltime(less than 200ps) and a width determined by the length of the transmission line and switching efficiency limited by the load has been obtained.
