摘要

The aim of this paper is to present a study of the thermal lens technique in quantifying the thermo optical coefficients: ds/dT (optical path change with temperature), thermal diffusivity and conductivity of PbO-Bi2O3-Ga2O3-BaO glasses doped with Yb3+. The thermal lens results indicate that the heat generation, as a function of the incident wavelength, resembles the absorption band F-2(7/2) -> F-2(5/2) of Yb3+. Thermal diffusivity of 2 x 10(-3) cm(2)/s and thermal conductivity of 4.5 x 10(-3) W/K cm were obtained and are similar to other glasses already reported in previous literature. The results emphasize that the thermal lens technique can be a powerful tool to study the heat generation of new glassy systems. (c) 2006 Elsevier B.V. All rights reserved.
