COHERENT RESONANCES OF SATURATED ABSORPTION ON THE TRANSITION WITH LEVEL MOMENTA J=1/2 IN UNIDIRECTIONAL WAVE SPECTROSCOPY

E.G. Saprykin, A.A. Chernenko

The physical processes that form the saturated absorption resonance spectra on the atomic transition with level momenta J=1/2 in the field of unidirectional waves of arbitrary intensities with a change in the direction of their polarization are studied both analytically and numerically. It is shown that the anomalies of the nonlinear resonance spectra and the processes forming them are determined by the direction of light wave polarizations, openness degree of the atomic transition, and the saturating wave intensity. The conditions are found under which the nonlinear resonance is exclusively coherent, due to the magnetic coherence of transition levels.
