【 摘 要 】

Series of (90% – x) TeO2 – 10% TiO2 – x Bi2O3 (x = 0, 5 and 10 mol %) tellurite laser glasses doped by Yb2O3 were prepared. The spectroscopic properties were characterized by the Raman spectrum, absorption spectrum and the fluorescence decay curves, respectively. The research achievements show that with the increase of Bi2O3, the emission cross-section increases from 1.20 to 1.31 pm2, the fluorescence lifetime decreases from 0.68 to 0.65 ms firstly, and then increases to 0.70 ms. These properties show that the system of 80% TeO2-10% TiO2-10% Bi2O3 glasses may have potential be used as Yb2O3 doped large emission cross-section gain medium for solid laser.
