Abstract

We replaced Se in Ge_11.5As₂₄Se_64.5 glasses with S, and prepared several Ge_11.5As₂₄S_64.5·xSe_{64.5·(1 - x)} glasses with x = 0, 25%, 50%, 75% and 100%, respectively, in order to improve the laser damage threshold in the glasses. Through the results of various measurements, we concluded that the substitution of Se with S in the glasses has negligible effect on glass transition temperature T_g and elastic properties. However, this could change the optical band gap and linear and nonlinear refractive indices of the glasses and significantly improve the laser damage threshold.
