Crystal quartz for high-intensity wavelength conversion was evaluated. The pure durability of crystal quartz for a sub-ns pulse region at 1.064µm irradiation was measured as 602 GW/cm2, which was 2-times higher than undopedd YAG crystal. QPM-structured quartz constructed by multi-plate stacking was evaluated by sub-ns high-energy MCL-MOPA pumping. Availability of crystal quartz for high-intensity pumping at 17.3 GW/cm2 could be demonstrated. QPM quartz is expected for both high-intensity operation and short-wavelength conversion.
