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 4I13/2 -> 4I15/2 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.
