    摘要: A process of surface-treating a laser glass is disclosed which comprises coating a specific sol solution obtained by hydrolysis and partial polycondensation of a mixture containing a metal alcoholate on the glass surface and heating the coated glass to form a glassy coating, wherein the glass surface may be treated, prior to the coating, with an alkali aqueous solution and with an aqueous solution of phosphoric acid in sequence, or the coating and the heating may repeated to form a double- or multilayer of the same or different kind of glassy coatings. The thus treated laser glass has increased thermal shock resistance and water resistance.
