In this work, we report the optical properties of Yb3+ ions in halogeno-sulfide glasses of composition (75-x)GeS2-25Ga(2)S(3-x)CsCl (x = 5%, 10%, 15%, 20%, and 25% CsCl). This study includes an analysis of the influence of halide concentration on the absorption and emission cross-sections and lifetimes of Yb3+ ions. A blue shift of the absorption and emission bands and a decrease of the absorption and emission cross-sections and transition probability are observed as the halide concentration increases in the glass.
