中文摘要：
采用高温熔融工艺制备了Yb3＋掺杂硅酸盐玻璃。转变温度和软化温度分别为593．2℃和783．4℃。测试了玻璃的吸收光谱和发射光谱，采用Fuchbauer—Ladenburger（F-L）方法计算了Yb3＋的积分吸收截面和受激发射截面及荧光寿命。玻璃的常规性能测试和光谱特性研究表明，所制备的玻璃材料能够满足光纤预制棒的使用要求。
英文摘要：
Several kinds of Yb3＋-doped silicate glass were produced by the melting process at high temperature. The transformation temperature and the intenerate temperature were 593.2 ℃ and 783. 4 ℃, respectively. The glass absorption and emission spectra were tested. The integral absorption cross section, the stimulated emission cross section and fluorescence lifetime of Yb3＋ were calculated by Fuchbauer-Ladenburger （F-L）method. Study on the conventional performance and spectral characteristics of the glass materials proved that they could meet the application requirements of optical fiber.
