Abstract

It is well known, metallic plasmas created during welding with high power lasers are very important for the welding process. During recent years, we have been trying to characterize these kinds of plasmas, in order to get a better comprehension of the absorption of laser light by a steel target during welding with a CO₂ laser. A complete spectroscopic characterization (electron density and temperature) of these types of plasmas was achieved, in spite of the lack of spectroscopic data for metallic lines. Only one iron line was found to be well calibrated. The problem of electron density for iron plasmas has been solved with this line. This is not the case of titan.
