AbstractThe use of lasers to achieve transformations at interfaces, either on solids under air, controlled atmospheres or a diversity of liquid environments, is evolving at a fast pace and in-line with recent advances in photonic technologies. The singular properties of lasers, which provide a choice of emission parameters, such as emission wavelength, pulsed or cw mode and pulse width, together with the use of optomechanical means to scan in beam or line fashion, are ideal in order to trigger physico-chemical phenomena which are not available with alternative methods and are, at large, based on thermally activated processes. Recently developed methods in our Laboratories include those that are based, on the one hand, on strongly photothermal interactions; on the other, on mixed type interactions, where photothermal, photophysical and, in some cases, photochemical types may cohexist. In the former case, a solid may melt and, with the controled laser movement, directionally solidify into a material with controlled microstructure. In the latter case, an ablation process with extreme physical or chemical consequences may be triggered and be localised at the irradiated interface. A brief description of the phenomena behind laser-solid interactions will be presented, along with results obtained with the Laser Ablation Backwriting (LAB) method and applied to surface modification of glass. This has been recently developed in order to modify physico-chemical and functional properties of glass surfaces at large, based on this fully scaleable method. In particular, selective metallization of glass surfaces will be addressed in this talk.
