Abstract: We fabricated successfully microstructures on graphene sheet by using multiplex interfering femtosecond laser beams. The symmetry, period and the fabrication depth are all influenced by the amount of interfering femtosecond beams. Using this method we fabricated grating-like microstructures and square lattice. In addition, we developed double-exposure technique with 2-beam interference and achieved square and rhombus lattice on graphene sheet.

 

Keywords: femtosecond laser beams; interference; grating; double-exposure; graphene sheet; periodic microstructure; nanomanufacturing; nanotechnology.
