Ultrafast Laser Processes at Interfaces:Physico-Chemical Aspects and Applications Intensive research has been undertaken in ultra-short laser microprocessing particularly of inorganic and biological samples [1]. Near-ablation threshold investigations were concerned with the generation of periodic nanostructures and their correlation with physico-chemical properties of the solid phase such as e.g. the material-dependent surface energy [2,3]. Electrolyte containment of solid interfaces showed strong influence on the resulting micro- and nanostructures. The phenomena are discussed in respect to the surface free energy in dependence of material composition and interfacial structure. |
