摘　　要：研究了掺Yb^3＋硅酸盐玻璃的吸收光谱和发射光谱，测量的荧光寿命为1．02ms，计算和探讨了Yb^3＋的积分吸收截面和受激发射截面及荧光寿命随样品厚度的变化趋势。激光性能评估表明，掺Yb^3＋硅酸盐玻璃具有小的激发态最小粒子数（0．087），较小的最小泵浦强度（3．11／kw·cm^-2）和较大的激光增益系数（2．66pm^4·ms），是较为理想的掺Yb^3＋激光材料。The absorption and fluorescence spectra of Yb^3＋ -doped silicate glasses were studied, and fluorescent time were measured 1.02 ms. The integrated absorption cross section, stim-ulated emission cross section and fluorescent time were calculated and discussed with thickness of Yb^3＋ -doped silicate glasses. Evaluation of laser properties showed that the glasses had the minimum fraction of Yb^3＋ ions（0. 087）, the minimum absorbed saturation intensity（3.22/kw·cm^-2）and larger gain coefficience（2.66 pm^4·ms）, so they were desirable Yb^3＋ -doped material.
