Coherent Effects in Nonlinear Spectroscopy of Counterpropagating Waves
摘要
Abstract—
The physical processes of formation of the saturated absorption resonance spectrum on degenerate transitions of atoms in the method of a probe field of counterpropagating waves of arbitrary intensity are studied. It is shown that the effects of magnetic coherence of levels induced by counterpropagating wave fields can change the shape of the absorption resonance up to its complete inversion.
