Finite element analysis of nanosecond pulsed laser ablation of various materials

Abstract

Purpose The purpose of this paper is to analyse nanosecond pulsed laser ablation on both metallic materials and non-metallic materials; a comparison between metallic materials and non-metallic materials has also been included. Design/methodology/approach In this paper, FEM method has been used to calculate the result by means of the finite element method. Furthermore, all the analyses are based on thermal theories. Findings The paper presents a comparison of metallic and non-metallic materials. Besides, the effect of how laser parameter changes would influence the ablation depth has also been assessed. Research limitations/implications All studies in this paper are based on classical thermal theories. Thermal theories are not applicable some times. Originality/value With the results of this paper, suggestions are made so that experiments and manufactures could be optimised and improved.
