Crystal quartz has excellent optical properties as short absorption edge and high laser-damage threshold, which are suitable for intense pulse-laser pumped wavelength conversion by artificial quasi-phase matching structures. We present on initial evaluation of second-harmonic green generation with 14.9 kW peak power using periodic laminar structured quartz, pumped by sub-nanosecond pulse with focused intensity > 100 GW/cm.
