Abstract
Large-aperture and high-energy seeded operation of optical parametric generators (OPGs) based on quasi-phase-matched crystals is presented. High-quality seeded outputs as evidenced by narrow bandwidth and low divergence are demonstrated with energies up to 12.5 mJ in the signal and the idler. The results of OPG devices operating in a partially seeded regime are also presented to give a general prescription for successful seeding at high energies.
