AB - A novel optical coating developed to reduction of specular reflection has been developed using the sol-gel route. The sol-gel antireflective (AR) coating is made from tantalum and silicon oxide-based solutions. First layer is deposited from a solution based on polymeric tantalum oxide. Second layer is containing silica polymeric matrix in order to get a double-layer optical stack. Sol-gel synthesis have been carried out starting from cheap precursors in order to produce metallic alkoxide-based solution, each one suitable for liquid-deposition technique use such as dip-coating. After layer deposition, a curing step is required. Both thermal and UV-curing could induce layer densification and generate final coating properties. Thermal baking step does not exceed 150 degrees C temperature. This two-layer antireflective coating has been optimized to offer scratch- resistance allowing easy-cleaning and also broadband anti- reflection property onto various substrate. Experiments of AR-coating deposition onto large-area high-power laser glass plates is described. Based on calculations, the amplification yield using such a sol-gel coating onto LMJ- blastshields is evaluated to be ca. 7 percent.
