Determination of irradiation parameters for laser-induced periodic surface structures

► We present an approach for the determination of irradiation parameters for laser-induced periodic surface structures. ► The approach is based on accumulated fluence and consists of two steps. ► (1) Determination of fluence domain boundaries and (2) approximation of irradiation parameters. ► The approach is required to apply LIPSS for surface functionalization. ► We provide experimental evidence that the accumulated fluence has a decisive role in the spatial emergence of LIPSS.
