文摘

The 100/200 ns fiber laser was used to structure nickel surface. We found there is an optimum scanning speed for the highest absorbance. The processing time was significantly shortened by a scanning speed up to 100 mm/s. The micro/nanostructured broccoli-like clusters with high absorbance was fabricated. Self-organized periodic arrays were created by laser crossing scans treatment.
