Description

technical field [0001] The invention belongs to the technical field of optical glass, and in particular relates to ytterbium-erbium co-doped phosphate glass and its preparation method and application. Background technique [0002] In recent years in communication networks, most commercial fiber optical amplifiers (EDFA) are made of silicate glass, which has a relatively narrow bandwidth emission (35nm) resulting in a narrow curve, which limits its Applications in broadband transmission. Therefore, the need for more efficient fiber amplifiers and flat gain spectra has prompted researchers to explore more new glasses, especially Er-doped phosphates, bismuthite glasses, and tellurites have attracted much attention because of their use in The 1.53nm band has a large stimulated emission cross section and a wide fluorescence band. [0003] Phosphate glasses have received considerable attention due to their potential applications in optical data transmission, detection, sensing, ...
