Abstract：Yb3+-doped silicate glasses were prepared at high temperature，which had a small non-linear refractive index coefficient n2(1.62)，lower transformation temperature and lower softening temperature(540 ℃ and 585 ℃，respectively). The absorption spectrum from 850 to 1100 nm showed that the main peak was at 975 nm with two subpeaks near 908 nm and 944 nm, respectively. Emission peak was at 1 010 nm in the fluorescence spectrum with a 65.5 nm fluorescence half-line width. The integrated absorption cross section, stimulated emission cross section and fluorescence time were caculated to be 3.44×104 pm2,0.71 pm2 and 1.05 ms, respectively, which satisfy the requirements of laser glasses.
