采用脉宽为35~65 fs,中心波长为800 nm的飞秒脉冲激光对经抛光的镍片进行表面扫描处理，并在金属表面上制备了彩色镍图案; 设置不同的激光扫描速度和能量密度扫描处理不锈钢表面，亦制备了彩色图案。介绍了实验过程，分析了实验结果，扫描电子显微镜（SEM)形貌分析显示，经过飞秒激光扫描处理的金属表面出现了纳米量级的激光诱导周期表面结构（NC-LIPSS），在镍上形成的结构周期约为480~510 nm，在不锈钢上形成的结构周期约为480~540 nm。

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.
