Abstract: The spectral properties in different concentration of Yb ions (0.5–5mol%)-doped silica glasses are explored in this paper. The glasses are prepared by traditional melting method. The absorption spectra and the fluorescent lifetime (τ f) are measured at room temperature and low temperature (18K). The stimulated cross-section (σ emi) and potential laser properties (β min, I sat, I min) are calculated based on the absorption spectra. The absorption cross-section (σ abs) are in the range 1.08×10−20– 1.18×10−20 cm2 in different glasses, the fluorescence lifetime (τ f) change from 1.9 to 1.2ms with the increase of Yb3+ concentration. The potential laser properties indicate that lead silica glass is a good host for highly Yb ion doping glass. [Copyright &y& Elsevier]
