Abstract
An optical parametric generator based on periodically poled and pumped by a -wavelength laser has been demonstrated. Pump pulses of 50-ns duration of 50-Hz repetition frequency were converted into signal and idler pulses in the wavelength range in a double-pass pump configuration by a 5-cm-long quasi-phase-matched crystal. An average pump power of 180 mW generated 30-mW average signal power at wavelength, corresponding to 16.7% signal conversion efficiency.
