Abstract
Fabrication of a thick periodically poled MgO-doped device with a period for mid-infrared generation was demonstrated. The periodic structure was evaluated by measurement of second-harmonic generation with the coefficient. Optical parametric oscillation using this device with an uncoated aperture and a effective length realized a high-energy output of for both signal (wavelength ) and idler waves with a 72% slope efficiency at pumping of a Q-switched Nd:YAG laser with a pulse duration.
