Nanosecond laser ablation of bulk Al, Bronze, and Cu: ablation rate saturation and laserinduced oxidation

In this work we report about the characteristics of nanosecond laser ablation, in atmospheric air, of bulk Al,Bronze, and Cu. Average per pulse laser ablation rate and its dependence on ablation depth is presented forthese three metals. We will demonstrate and discuss some distinctive features of th...

Descrição
Resumo:In this work we report about the characteristics of nanosecond laser ablation, in atmospheric air, of bulk Al,Bronze, and Cu. Average per pulse laser ablation rate and its dependence on ablation depth is presented forthese three metals. We will demonstrate and discuss some distinctive features of the ablation saturation effectof the above metals. We will also present results on laser-induced oxidation of the metals which results off theablation event. We studied the laser-induced oxidation effect through energy-dispersive X-ray spectroscopy(EDS or EDX). The EDS results presented here show that the laser irradiated metals oxidize during theablation process; the metals oxidize to different degrees showing a strong dependence on the net deliveredlaser fluence.
