研究了Yb3+/Er3+共掺60P2O5-15BaO-10Al2O3-5ZnO-10R2O(R=Na, K)以P2O5为主体的磷基有源光纤材料的光谱性质, 以及不同Yb3+/Er3+掺杂浓度对光谱性质的影响规律。当Er3+浓度为9.100×1019 /cm3、Yb3+的掺杂浓度为5.407×1020 /cm3、Yb3+/Er3+浓度比为6∶1时, 玻璃样品在1 531 nm处的受激发射截面最大, 为6.17×10-21 cm2。同时, 其荧光寿命为9.73 ms, 荧光半高宽为53.16 nm, 发射截面与半高宽的乘积为3.28×10-32 m3, 综合性能最佳。

Yb3+/Er3+ co-doped 60P2O5-15BaO-10Al2O3-5ZnO-10R2O(R=Na, K) phosphorus based material with P2O5 as the principal ingredient were researched. The spectroscopic properties of the fiber material and the effect of Yb3+/Er3+concentration ratios on the spectral properties were researched. When Er3+ concentration is 9.100×1019 /cm3, Yb3+ concentration is 5.407×1020 /cm3, and their optimum concentration ratio is 6∶1, the largest stimulated emission cross section is obtained for 6.17×10-21 cm2. At the meantime, the fluorescence lifetime is 9.73 ms, full width half maximum (FWHM) is 53.16 nm, and the product of emission cross section and FWHM is 3.28×10-32 m3, which indicates this material has the best performance.
