Abstract

Laser beams are nowadays largely used for applications like cutting, machining, nano- machining, nano-structuring, and analysis of material characteristics. Due to the high laser intensity, these processes usually involve the formation of plasma on the surface of the irradiated targets, which is accompanied by laser ablation, i.e. in the removal of material from the surface. Such material forms an ablation plume and can then be deposited on particular substrates placed at some distance from the irradiation point. This brings to the coating of the surface and can be used for the formation of thin films or multi-layers. Also, nano-particles can be produced by laser ablation under specific interaction conditions. This paper initially focuses on laser ablation, especially in the short laser pulse regime (τ p ≤ 1 ps) using the classical “two temperature model”, and second to study the generation of nano-particles following a specific thermodynamic path of the irradiated material.
