Effects of coupled atomic states on the resonance scattering of radiation

Creator:

Srivastava, Rajendra Prasad

Abstract:

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...

Decay of atomic states strongly coupled by an oscillating field

Creator:

Greenwood, William Graham

Abstract:

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...

Response of two-level atoms to intense amplitude modulated laser beams

Creator:

Blind, Barbara

Abstract:

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...
