We replaced se in Ge11.5As24Se64.5 glasses with S, and prepared several Ge11.5As24S64.5 (center dot) Se-x(64.5) (center dot) ((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.
