Nanostructuration par laser femtoseconde dans un verre photo-luminescent

Abstract : The aim of this work is the study of the interaction between a femtosecond laser and a special photosensitive medium : a silver containing phosphate glass, also called photo-luminescent (PL) glass. A new approach allowing to write, inside the PL glass, 3D silver nanostructures with feature size down to the diffraction limit is presented. Based on optical and structural measurements at different time and spatial scales, the mechanism of the formation of these nanostructures is described. A subtle interplay between nonlinear absorption and thermo-diffusion effects is found to be the key of the mechanism. The second part of this work relies on the optical properties (linear and nonlinear) and few applications of the silver nanostructures. More particularly, the enhancement of their nonlinear properties is used for three dimensional optical data storage.
