Abstract

Laser processing of metallic surfaces in use of fs pulse laser has been shown to produce novel effects. We demonstrate nanoscaled surface texturing effects of aluminum alloy 2024 using femtosecond pulse laser irradiation. The laser source is a 496 nm dye laser with 500 fs pulse width in a range of laser output fluence from 0.02 to 10 J/cm². Results indicate that the surface futures, ranging from nanoscale to 20 microns, can be developed through variation intensities. Advantages of femtosecond pulse laser for precise metal microstructuring and physical mechanisms for ultrashort pulse laser ablation have been discussed.
