We report a new photoconductive switch having an average output power of , an instantaneous bandwidth of , an output pulse width of , a peak output power of , and an optical-to-electrical conversion efficiency of when pumped by a palm-sized mode-locked free-space laser at with an average power of and an optical pulse width of . The switch is made from an epitaxial layer inside a resonant optical cavity and coupled to a planar three-turn square spiral antenna.
