ResumoA series of new glasses of 70TeO2-(20-x) ZnO-xWO3-5La2O3-2.5K2O-2.5Na2O (mol %) doped with Yb3+ is presented. Thermal stability and spectroscopic properties of Yb3+ ions have been measured. It found that 70TeO2-15WO3-5ZnO-5La2O3-2.5K2O-2.5Na2O composition glass had better thermal stability ((Tx−Tg)>160 °C) than 75TeO2-20ZnO-5Na2O glass, high-stimulated emission cross-section of 1.32 pm2 for the 2F5/2→2F7/2 transition and existed measured fluorescence lifetime of 0.93 ms and the broad fluorescence effective linewidth of 74.5 nm. Evaluated from the good potential laser parameters, this system glass is promising for miniature solid fiber lasers or high-peak power and high-average power lasers, also for wave-guides or tunable lasers.
