Abstract

The photo-elastic constants (PEC) of BaO-P2O5 glasses with 50-57 mol%BaO were determined at 633 nm using a frequency stabilized transverse Zeeman laser. Measured PEC was found to vary from 0.15 to 0.63×10-12 Pa-1, depending on composition. The concentration effects of OH, Al2O3 and BaO on PEC are studied. PEC increases with increasing Al2O3 concentration for metaphosphate glasses with BaO/P2O5=1. On the other hand, PEC decreases monotonically with increasing BaO concentration. An empirical equation to predict PEC from glass composition is proposed. The correlation between PEC and glass structure, as evaluated by Raman spectroscopy is qualitatively discussed.
