Abstract

Gallium lanthanum sulfide-based glasses are attractive for new laser and nonlinear optical applications at near Infrared region. Refractive indexes were measured for Ga2As3-La2S3 and Ga2S3-La2O3 glasses in the range of 0.5 and 1.7µm using the minimum deviation method. Data is analysed by Wemple and Didomenico equation. These glasses have relatively large average electronic bandgaps E in comparison with other chalcogenide glasses. Possible origins of these features are discussed.
