The development of a picosecond GaAs photoconduotive switch is reported. The switch consists of a miorostrip transmission line formed on Cr-doped semi-insulating GaAs with a small gap (-20μm) in the stripline. As the source of optical pulses used for preliminary evaluation of the switch, a synchronously pumped Rh6G dye laser was used.
