Paper Abstract

Excimer laser irradiation has been shown to yield unique results when used to process metallic surfaces. We have investigated surface texturing effects on 2024 aluminum alloy specimens. A pulsed XeCl excimer laser was used to generate irradiation fluences ranging from well below to substantially above the ablation threshold. Our results indicate that novel micron-dimensioned surface texturing is achieved over selected fluence regimes. At elevated fluences, texturing is lost due to the extensive surface- melting process. Under certain conditions, sub-micron dimensioned surface structures were generated.
