Abstract Yb3+-doped borosilicate glasses were prepared at high tempreture. The absorption spectra and fluorescence spectra were measured at room temperature. The integrated absorption cross section, stimulated emission cross section and fluorescent time were calculated. The results showed that the main peak wavelength was 975.15 nm in absorption spectra with one subpeak near 937.17 nm; emission peak was at 977.15 nm in fluorescence spectra with one subpeak near 997.42 nm; with increasing the sample thickness from 0.5 to 5 mm, luminescence intensity became greater, and the peak shifted to longer wavelength from 995.79 to 999.02 nm. The effective line width of fluorescence increased from 34.64 to 54.50 nm; Fluorescence lifetime decreased from 1.04 to 1.00 ms.
