Quarter wavelength optical designed single layer and double-layer sol-gel derived metal oxide based antireflection (transmission, 98-99% at 1054 nm) coatings have been fabricated on quartz glass optics. In addition, high reflection (>55% at 1054 nm) of 5-layer coating on quartz glass has been developed in the reporting period. The coatings showed high laser damage threshold value.
