Concentration dependences of elastooptic coefficients of germanate glasses containing lead and bismuth oxides

Abstract

Concentration dependences of elastooptic coefficients of lead — bismuth — germanate glasses with compositions from virtually the entire range of glass formation in the system PbO — Bi2O3 — GeO2 are investigated. Partial elastooptic coefficients of the oxide ingredients of the investigated glasses are determined. The results are interpreted with consideration of the nature of the elastooptic interaction in glasses subjected to uniaxial stress. The data can be used for designing compositions of optical media for the light and acoustic lines of acoustooptical devices.
