Paper Abstract

This paper concerns the characterization of a plasma by spectroscopic method. The study uses a spectrograph coupled to a gated optical multichannel analyzer (O.M.A) in order to obtain temporally and spatially resolved optical emission spectra of laser-induced aluminum and carbon plasmas. Laser-produced plasmas are described with Local Thermodynamic Equilibrium (L.T.E) assumption. Electron temperature and density informations are evaluated from spectroscopic records. Absorption coefficients have been estimated for CO2 and visible radiations
