Abstract
In this work, the thermal and spectroscopic properties of Er3+-doped oxyfluorite glass based on AMCSBYT (AlF3–MgF2–CaF2–SrF2–BaF2–YF3–TeO2) system for different TeO2 concentrations from 6 to 21mol% is reported. After adding a suitable content of TeO2, the thermal ability of glass improves significantly whose ΔT and S can reach to 118°C and 4.47, respectively. The stimulated emission cross-section reaches to 7.80×10−21cm2 and the fluorescence lifetime is 12.18ms. At the same time, the bandwidth characteristics reach to 46.41×10−21cm2nm and the gain performance is 63.73×10−21cm2ms. These results show that the optical performances of this oxyfluorite glass are very well. Hence, AMCSBYT glass with superior performances might be a useful material for applications in optical amplifier around 1.53μm.
