Abstract
The build-up time of the thermal lens effect induced by a Gaussian beam in the DO3-doped sol-gel system xTiO(2).(100 - x)SiO2 at different composition s, both in the liquid and gel phases has been measured in a Z-scan geometry . While the pure titania samples show a minimum of the thermal diffusivity, a maximum is found for x approximate to 30. The sol to gel transformation leads to an increase of the build-up times at all compositions. (C) 1999 El sevier Science B.V. All rights reserved.
