Descripción
In this work, a fitting algorithm was implemented and applied to analyze emission line shapes in laser-induced breakdown spectroscopy. By modeling emission spectral lines, the optical thickness was calculated for each line of interest and the intensity line profileswere computed and matched to measured spectra. The algorithm was applied to analyze the experimental profiles of a hydrogenH_ line at 6562.8 Å, and the resonant lines of Mg II at 2795.5 Å and at 2802.7 Å. Spectroscopic information was obtained about the physical processes occurring in the plasma, such as self-absorption and Stark broadening. The results demonstrated the potential of the developed method to provide valuable information in plasma spectroscopy for both fundamental and applied research.
