Photoconductive Frequency Agile GaAs Impulse Device

Abstract

The feasibility of generating frequency agile impulses has been successfully demonstrated using a monolithic, photoconductive GaAs impulse device. Two time-delayed optical pulses from a mode-locked Nd:YAG laser, delivered by two different lengths of optical cables, were used to turn-on and turn-off the device. The time interval between the "on"-laser pulse and the "off''-laser pulse was varied, resulting in a corresponding change in the output electrical pulsewidth which ranged from 2.1 ns to 4.9 ns.
