Abstract The absorption, stimulated emission cross section and potential
laser parameters of heavy metal silicate glasses doped with Yb3+ ions have been investigated. The emission cross section has been evaluated by using the measured absorption spectra and principle of reciprocity. It is found that Yb3+ in SiO2-Bi2O3-B2O3 glass has high stimulated emission cross section of 0.9 pm2 for the 2F5/2 → 2F7/2 transition and exists short measured fluorescence lifetime of 0.78 ms. On the other hand, the stimulated emission cross section of Yb3+-doped SiO2-PbO glass was 0.49 pm2. Its measured fluorescence lifetime was 2.00 ms. Evaluated from the good potential laser parameters, Yb3+-doped SiO2-PbO glass may be a good candidate for fibre laser applications.
