Abstract We investigate the absorption, stimulated emission cross section and potential laser parameters of Yb³⁺ doped gernano-silicate glasses (GSY glass). The emission cross section is evaluated by using the measured absorption spectra and the principle of reciprocity. It is found that Yb³⁺ in GSY glasses has high stimulated emission cross section of 0.5-0.65 pm² near 1020 nm and exists long measured fluorescence lifetime of 1.20-2.00 ms. Compared with other glass hosts, the GSY glass exhibits excellent general spectroscopic properties for Yb³⁺-doped double-cladding fibres.
