Abstract: Method and devices using lasers to reduce reflection of transparent solids in the optical spectrum, coatings and devices employing transparent solids are disclosed. The lasers are used to shape surfaces of the transparent solid materials by raising the temperature of the material to around the melting temperature, and thereby generate desired target nanostructure two-dimensional antireflection pattern arrays on the surfaces. The laser fluence value, wavelength, repetition rate, pulse duraction and number of consecutive laser pulses per focus spot are selected, and a desired focus spot distribution on the surface of the transparent solid material is identified. The transparent solid material is relatively translated to generate the desired nanostructure two-dimensional pattern array.
