Paper Abstract

The role of the plasma during laser materials interaction is studied using emission spectroscopy. The experiments were carried out in two stages: firstly, with a pure argon plasma and secondly with an aluminum target. The electron temperature distribution and electron density were determined. The experimental results were used to estimate laser attenuation and refraction as the beam propagates through the plasma column. Thus, transmitted energy and energy distribution on the surface were determined. This is expected to be a more realistic input for transport phenomena models based on absorbed energy.
