In this paper, a new method for studying of aluminum thick plasma in LTE condition is introduced. The presented method calculates very simple and accurate the plasma parameters such as temperature, particle densities, shock wave expansion and instrumental function of system from the data of the spectral self absorbed lines. The LIBS experiment is done on aluminum sample at atmospheric air by combination of two techniques of spectroscopy and shadowgraphy. It should be mentioned that in this calculation, the plasma parameters can be evaluated exactly when electron density, plasma length and three intensities of spectral lines from specific element were obtained from experiment.
Keywords: Shadowgraphy, Laser induced breakdown spectroscopy, Self absorption.
