Influence of Glass Composition on the Refractive Index Change upon Photothermoinduced Crystallization

Influence of Glass Composition on the Refractive Index Change upon Photothermoinduced Crystallization

The influence of the main components (SiO^sub 2^, Al^sub 2^O^sub 3^, ZnO, and Na^sub 2^O) of a photothermorefractive glass matrix and Br^sup -^ions on the change in the refractive index is studied in the course of photothermoinduced crystallization in glasses. The optimum concentrations of these com...

Zusammenfassung:The influence of the main components (SiO^sub 2^, Al^sub 2^O^sub 3^, ZnO, and Na^sub 2^O) of a photothermorefractive glass matrix and Br^sup -^ions on the change in the refractive index is studied in the course of photothermoinduced crystallization in glasses. The optimum concentrations of these components at which the change in the refractive index is maximum are determined. The regularities revealed are explained within the modern concepts of the structure of polychromatic glasses and the nature of the photothermorefractive effect.[PUBLICATION ABSTRACT]
