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,
