Abstract: Mode-mismatched Thermal Lens (TL) measurements were performed in 70TeO 2-19WO3-7Na2O-4Nb2O5 (% mol) tellurite glasses doped with either Er3+ or Tm3+ and co-doped with Er3+/Tm3+ ions. Thermo-optical parameters (D, K, ds/dQ and ds/dT) were obtained in function of thulium concentrations (0.39-1.6) × 10 20 ions/cm3. For Er 3+/Tm3+ co-doped tellurite glasses, D and K values are practically independent of the Tm3+ concentrations used in this study. The average values of D and ds/dT obtained for tellurite glasses are: (3.1 ± 0.2) × 10-3cm2/s and (16 ± 3) × 10-6K-1, respectively. © Springer Science+Business Media, LLC 2007.
