Formation of laser induced periodic surface structures (LIPSS) on Ti upon double fs pulse exposure

Popis výsledku v původním jazyce

Recently a parametric decay model was proposed in order to foresee LIPSS interspaces, and experimental results are in reasonable agreement. To confirm the possibility assumed by the model of pre-formed plasma generation, Ti surface was irradiated by a femtosecond (fs) laser beam composed by double fs pulses, with a fixed delay of 160 fs. The fluence of the first pulse (F-PP), responsible for surface plasma formation, was varied in the range 10-50 mJ cm(-2) and always kept below the LIPSS formation threshold fluence (F-LIPSS) of Ti for 50-single-shots exposure. The fluence of the delayed pulse (F-LP), responsible for LIPSS formation, was varied in the range 60-150 mJ cm(-2) and always kept above F-LIPSS. Regardless the specific fluence F-LP of the delayed pulse, the interspace of the grating structures increases with the increase of F-PP, that is the increase of the surface plasma density. This tendency suggests that a variation of the surface plasma density, due to a variation of F-PP,
