A series of new glasses of 70TeO22-(20-x) ZnO-xPbO-5La22O33-25K22O-25Na22O (x=0,5,10,15, 20mol %) doped with Yb22O33 is presented. Thermal stability, spectra and laser properties of Yb3+3+ ions have been measured. It has been found that the glass with x=15 has a good thermal s tability ((Txx-Tgg)>195℃), high stimulated emission cross -section of 125pm22 for the 22F5/25/2 →22F7/27/2 transition and a long fluorescence lifetime of 094ms and a broad fluorescence effective linewidth of 72nm. From the viewpoint of good potential laser parameters, it is desirab le to have high-average power and short pulse tunable laser, which can be achie ved by doping with Yb22O33.
