Abstract: Abstract Laser ablation is the process of removing material with very intensive, pulsed laser radiation. It is a technology which gains increasingly greater importance for drilling, eroding, welding, structuring and marking of all kinds of materials. We study the process of laser ablation in a combined approach of molecular dynamics simulations and direct continuum modelling of the electron heat conduction. The method, boundary conditions and benchmarks are presented. We present ablation studies of aluminium and determine the ablation threshold, the melting dependence on pulse properties and cluster analysis of the evaporated material. We also study laser ablation of a complex anisotropic alloy.
