Resonance Shapes of the Saturated Absorption and Magnetic Scanning on Transition with J=1-J=2 in a Spectroscopy of Unidirectional Waves

Physical processes forming resonance spectra of the saturated absorption and magnetic scanning on transition with level moments J = 1- J = 2 in the field of unidirectional waves of arbitrary intensities are numerically studied. It is shown that the anomalies of nonlinear resonance spectra are determined by the character of wave polarizations and by the degree of openness of atomic transition, and the anomalies of the magnetic scanning spectra are due to the magnetic coherence of the lower state levels, and not to its transfer from the excited states, as previously thought.
