GLASS SEALING WITH TRANSPARENT MATERIALS HAVING TRANSIENT ABSORPTION PROPERTIES

摘要

The transparent glass-to-glass hermetic seal is formed by sealing the interface between two glass substrates and providing a low melting temperature sealing glass with irradiation of the interface with laser radiation. Absorption by the sealing glass and induced temporal absorption by the glass substrate along the sealing interface cause local heating and melting of both the sealing glass layer and the substrate material, resulting in the formation of a glass-to-glass weld. . Due to the temporary absorption by the substrate material, the sealing area is transparent upon cooling.
