Abstract
We reported femtosecond laser-induced self-organized micro/nanostructures on Zr64.13Cu15.75Ni10.12Al10 amorphous surfaces. A set of process methods that induced sub-wavelength LIPSS (laser-induced periodic surface structures) structures and SWPSS (super-wavelength periodic structure) nearly twice the wavelength using 1030 nm wavelengths were observed. Using linear scanning can completely cover a layer of micro/nanostructures on the surface. Clear surface structures can be observed throughout the laser ablation area, and their cycles and structural fluctuations can be controlled by process parameters. The causes and structures of the two micro/nanostructures were discussed.
