Dmitri V. Gaidarenko, Alexei G. Leonov, A. A. Panteleev +2 more

An experimental study of the propagation of intense laser light in a resonant medium (sodium vapor) has revealed a scattering component which is inconsistent with the Raman scattering spectra of a three-level system in an intense laser field. Spectral and angular characteristics of this component have been studied. It is shown that the occurrence of this component can be explained by a model of a resonant four-wave mixing.

Comments on the problem of anomalous fluorescence of atomic sodium vapor at a wavelength of 589.6 nm

Н. И. Косарев

The problem of the laser-induced fluorescence of sodium vapor at a wavelength of 589.6 nm in the case of photoexcitation of a small volume of the medium by a laser beam has been solved numerically. The photon transfer from the zone of excitation to the periphery in the direction perpendicular to the direction of propagation of the laser radiation leads to a significant extension of the volume with a high density of excited atoms. The influence of this factor on the formation of the resonance fluorescence of sodium vapor is discussed.

The influence of quantum interference effects on the resonance fluorescence spectra of a degenerate three-level atom

A. A. Panteleev, Vl. K. Roerieh

The resonance fluorescence spectra of a degenerate three-level atom of the V -type in the field of an intense monochromatic wave with an arbitrary polarization composition are investigated. Analytical expressions are derived for the resonance fluorescence spectra, and the angular distribution of spontaneous fluorescence of atoms is analyzed for the D -line emitted by vapors of alkali atoms. It is shown that the number of lines in the spectrum may decrease in the case of the linear polarization of spontaneous radiation. The radiation relaxation operator is obtained for the D -line of alkali metals in the case when an atom is near the metal surface. Interference effects for such systems are analyzed.
