Abstract

Er³⁺/Yb³⁺co-doped tantalum-phosphate glass was prepared. Compared with the conventional phosphate glasses, the tantalum-phosphate glass posses higher glass transition temperature, and then chemical durability. Based on the measured absorption spectra, the absorption and emission cross sections for ⁴I_13/2 -> ⁴I_15/2 transition and some important radiative properties of Er³⁺ were calculated and discussed by using McCumber theory and Judd-Ofelt theory. The results show the peak values and effective bandwidth of emission cross section are larger and wider. These properties make Er³⁺/Yb³⁺ co-doped tantalum-phosphate glass much more attractive candidates for microchip lasers and integrated optical amplifiers.
