Abstract :
We report on the observation of terahertz (THz) radiation emitted from monoclinic bismuth vanadate (BiVO4) and gold (Au) thin film interfaces, irradiated with femtosecond laser pulses. The emitted terahertz pulses show a second-order dependence on the pump power. THz radiation was measured for different thicknesses of BiVO4 and the possible reasons for this thickness dependence are also discussed.
