Abstract

Photoconductive switch as the core high-voltage nanosecond electric pulse system. Semi-insulating GaAs photoconductive switch bias electric field in the initial conditions of 26.7 kV / cm by 1 ns, 20 'J light wavelength of 064 nm laser irradiation according to SRH model and finite element method calculation of the carrier sub-concentration, and photoconductive switch domain resistor consider Blumlein transmission line equivalent capacitor voltage changes in the time domain, conduct a Simulation of the output pulse. simulations and experiments show that, in the Blumlein transmission line discharge capacitance is very small the upper limit of the linear operating range (27.2 pF) case, the full capacitor discharge causes the switch of the light guide at least up to 26.7 kV / cm.
