Abstract
LIPSS as well as hierarchical structures were generated by applying picosecond laser irradiation on a stainless steel-304 probe in a confinement liquid medium. Periodicity modification from high to low spatial surface frequency LIPSS was observed by modifying the pulse repetition rate from 1.3 to 402 kHz at a constant fluence. One of the outcomes reported in this study was the wettability analysis of the processed area which yielded significative changes on the contact angle between a water drop and the treated surface showing a wetting transition from hydrophilicity to hydrophobicity as an effect of the multiple impact pulses.
