Abstract
In the context of a general investigation of the nonlinear optical pro perties of glasses, we report here the effect of introducing TiO2 in v arious silicate and borophosphate glass matrixes. A correlation study is carried out between the magnitude of the measured nonlinear indices n(2) of these materials and the local structure around titanium which can be deduced using XAFS analysis. This allows to point out that squ are-based pyramids are particularly efficient when present in borophos phate glasses.
