| Abstract: | Narrow atomic absorption lines of Ba, Cs, Mg, and Tl are recorded in an electrothermal atomizer with a graphite tube furnace
by the intracavity laser spectroscopy method. The conditions of applicability of this laser absorption method for reducing
the observed profiles of spectral lines to the true ones are found. Measurement of the integral absorption coefficient has
made it possible to determine the absolute number of free atoms of each element in the analyte volume at the maximum of the
absorption peak under optimum conditions of atomizer heating. The Voigt parameters are determined from the profiles of absorption
lines.
