Abstract

Laser-induced structural transformations such as transformation hardening, annealing, recrystallization, glazing, shock hardening, polishing (planarization), etc., are based on the high processing temperatures that can be reached during short heating and cooling cycles under high-power pulsed-laser or rapidly scanned cw-laser irradiation. Short processing cycles permit material transformations within thin films and surfaces without significant influence on the substrate or the underlying bulk material. In the case of surface absorption, which is a good approximation withcmany applications, the thickness of the heated zone is approximately described by the heat-diffusion length, l T.
