Paper Abstract

The generation of subnanosecond risetime pulses with 2 MW peak power at 1 kHz PRF has been achieved by triggering a hybrid pulser with a laser diode array. The hybrid pulser combines an optical switch centered in a metallized teflon disk that serves as an energy storage medium as well as a radial transmission line. Nearly 90 ofthebias voltage (10 kV) was delivered to a 50 ohm load impedance as a result of the variation of impedance of the radial line. Avalanche switching yielded 4 nano seconds pulses with a risetime of less than 500 picoseconds. _
