In the laser materials processing community, the modification of target surface morphology by impact of intense laser pulses has been of continuing prominence. In particular regular Laser-induced periodic surface structures (LIPSS) have been the subject of intensive research, aiming not only at the structure formation, specifically, but also on a broad range of applications, such as wettability modification, coloring, tribology etc.
Much less known in the laser community is, however, the fact that similar, almost identical structures are also obtained by ion sputtering, when energetic ion beams are incident on the surface.
The presentation will shortly present some results of ion induced periodic surface structuring. Then these will be compared to LIPSS, elaborating similarities and differences. Finally models for both interactions will be reviewed and compared.
