Femtosecond laser processing of micro- or nano surfaces: controlling tailored physical or chemical properties of materials

Photonic processes, particularly laser based material processing methods allow for a variety of possibilities to provide materials with novel characteristics. Especially laser beam sources, emitting ultra short laser pulses with durations in the femtosecond regime (10-15 s), enable the realization of such novel material properties. On this time scale the light – materials interaction is too short for an efficient heat transfer into the material.
