Abstract

In this work, we first presents a review of the work that research teams have developed in collaboration in order to determine the optical properties of plasmas during the recent years, and showing the achievements reached. The second part of this paper is devoted to one of these improvements, which is to include reabsorption of the radiation in the calculations of dense optically thick plasmas in non-LTE conditions. Two models recently developed for this purpose are presented. The quantitative study was focused on aluminum plasmas, which was obtained recently at LULI experiments.
