Paper Abstract

Laser ablation of aluminum alloy and stainless steel were investigated experimentally with a picosecond laser (1053 nm, 8.6 ps, 1Hz). We analyzed and compared the damage threshold and morphology of stainless steel and aluminum alloy. The single-pulse ablation threshold of stainless steel is higher than that of aluminum alloy. The ablation morphology are quite different under multi-pulse irradiation, and the micro-scale periodic surface structures are formed on the stainless steel surface but not on the aluminum alloy sample. The influence of metal thermodynamic properties on laser ablation characteristics is analyzed.
