Modelling of Plasma Temperatures and Densities in Laser Ablation Plumes of Different Metals

Laser ablation has many uses in industry, including laser drilling and thin-film deposition. However, the underpinning physics of not been fully elucidated. In particular, differences behaviour plasma plumes ablated from different materials, which material properties are related to plume characteristics, require further study. This paper presents results modelling photocatalytic materials using 2D hydrodynamic code POLLUX. The evolution key parameters such as density temperature is investigated when target changed titanium tantalum, zinc, copper, aluminium gold. It was found that atomic number significantly affected electron mass subsequent plume, with both increasing number, whilst other density, thermal conductivity melting did affect or particle plumes. These provide insights for future experiments where aim change material, but keep constant possible.
