- The field-dependent relaxation effects in the driven three-level atoms at arbitrary intensity and detuning of the driving field for all possible level configurations were studied. It was found that the physical origin of the field dependent relaxation is a dependence of relaxation rates on dressed atomic frequencies. Both the sign and the magnitude of the relaxation rates were drastically modified in case of level crossing. Dressed-state basis allowed for clear interpretation of the observed novel effects. In the limit of large driving field frequency detuning, the interpretation via specific kind of Raman scattering in bare-basis was also possible.
