Photoconductive switch with integral wavelength converter

Abstract

The photoconductive switch comprises a laser that generates light having a first wavelength and a photoconductive switch element arranged to receive the light generated by the laser as incident light. The photoconductive switch element includes a photoconductive layer and a wavelength conversion element. The photoconductive layer has a low absorptivity at the first wavelength. The wavelength conversion element converts the incident light into activating light having a second wavelength at which the photoconductive layer has a greater absorptivity than at the first wavelength. The wavelength conversion element is integral with the photoconductive layer, or is in contact with the photoconductive layer, or is both integral with and in contact with the photoconductive layer.
