Abstract

Abstract

The polished nickel surface was scanned by a femtosecond laser beam with a pulse width of 35~65 fs and a central wavelength at 800 nm, and the multi-color pattern was obtained. The same processing was done for the stainless steel at different scanning speeds and laser fluences. The experimental results were analyzed by Electron Scanning Microscopy(ESM). The results show that the surface of the colorful metals are full of laser-induced periodic surface structures covered with nanostructures(NC-LIPSS), and the NC-LIPSS period on the nickel surface is about from 480 to 510 nm and that of on the stainless steel is about from 480 to 540 nm.
