    摘要: The invention is directed to a glass composition and articles made from the composition that are both polarizing and photorefractive. The glass has, for example, a composition consisting essentially of, in weight percent (“wt. %”) of 70-73 SiO2, 13-17% B2O3, 8-10% Na2O, 2-4% Al2O3, 0.005-0.1% CuO,

    摘要: The invention is directed to a method for preparing visible light optical polarizers using a non-halide silver salt and any glass composition that the non-halide silver salts is soluble, provided that the glass composition, including the silver salt, was a halide content that is, on a molar basis, 10% or less than the silver content, on a molar basis, of the glass composition. The silver containing glass is hydrogen reduced prior to stretching to form an optical polarizer. The invention enables one to form a visible light polarizer having a polarizing layer thickness in the range 10-40 μm in which the silver particles have a surround index sufficiently removed from the blue polarizer region to allow good contrast.

    摘要: A method for laser patterning of a glass body, the method comprising the steps of: (i) providing a laser, said laser having an output beam at a laser wavelength λ; (ii) providing a glass body having optical density at of at least 1.5/cm at said wavelength; (iii) directing said laser output beam to (a) impinge on the glass body without ablating said glass, and (b) heat the glass body at a location proximate to said laser output beam so as to form a swell at this location; and (iv) etching this location.
