Type 2/Type 2 third-harmonic generation in KDP at high fluences in a 3-cm aperture
Abstract
We have tested high-threshold KDP in a type II/type II polarization mismatch THG configuration at fluences and intensities in a 3-cm aperture which approach Nova Upgrade levels. The purpose of this work was to demonstrate high efficiency, damage-free third-harmonic generation in the proposed Upgrade operating regime of 9 to 12 J/cm(exp 2) at a 3-ns pulse duration.
