Paper Abstract

Here we report the proposed by us concept for monitoring the atmospheric and Earth Hg and Pb pollution by means of Intracavity Laser Spectroscopy (ILS). The concept profits from the extremely high sensitivity of the ILS dye laser registration by preliminary excitation of the Hg(Pb) atoms to a suitable level to induce absorption at the analytical transition corresponding to the second dye laser emission spectrum. A theoretical proof is given on the possibility for two-step optical excitation from the ground state level.
