INFLUENCE OF THE SELF-ABSORPTION OF ATOMIC LINES ON THE DETERMINATION OF TEMPERATURE AND ELECTRON NUMBER DENSITY IN THE CASE OF A LASER INDUCED CaCl2 − WATER PLASMA

摘要
A spectroscopic study of the plasma plume created by a laser beam on the surface of a CaCl2 aqueous solution is presented. Optical emission spectra are recorded and temporally analyzed. The electron number density is determined from the Stark broadening of the nitrogen NI 746.8 nm atomic line and the temperature profile is obtained from the relative intensity of OI lines. To take into account the possible occurrence of the self-absorption phenomenon, the escape factor of each atomic line is computed and used to correct the measured line intensities in order to obtain reliable temperature and density profiles.
