The fast progress of ultrafast lasers with respect to the average output power and pulse energy opens the potential to significantly scale the productivity of laser-based high-precision materials processing. In order to tap the full potential of the next generation of these lasers, adequate process strategies have to be applied that take into account the fact that heat accumulation can significantly impair the quality of the processing result. By solving the heat-conduction equation and based on the assumption that the process limit can be characterized by a maximum acceptable temperature that should not be exceeded during processing, we will present fundamental scaling laws and discuss their practical implication on the applicable process parameters and process strategies.
