The conversion efficiencies of photovoltaic converters(GaAs, Si) for a pulsed nitrogen-pumped dye laser, a pulsed flashlamp-pumped dye laser, a flashlamp-pumped Nd:YAG and quartz tunsten-halogen filament lamp was studied. The conversion efficiencies were measured for different wavelengths of pulsed dye laser to verify the optimum wavelength, 0.87 μm for GaAs and 1.13 μm for Si photovoltaic converter, expected from the bandgaps of the photovoltaic converters. A significant reduction of the conversion efficiency is noted compared with that of continuous wave laser and solar radiation.
