The excitation and decay probabilities for resonance scattering
of radiation from an atom with two coupled excited states and one
ground state in an external static field are calculated as a function
of time and frequency. Various oscillatory behaviors are found in all
the probabilities. These oscillations depend on the...
Frequency distributions are calculated for the optical
decay of two atomic states which are coupled by a strong,
linear rf field. Both the rotating and the counter-rotating
components of the field are maintained throughout the
calculations. For strong fields many peaks are present in
the frequency spectrum and are explained...
The optical Bloch equations for a two-level atom in a laser
beam with an amplitude of arbitrary time dependence are derived in
the rotating wave approximation. The light scattered by the atom
is investigated for the special case of an intense, resonant laser
beam with a sinusoidally modulated amplitude. The...
