A thermal beam of lithium atoms excited to high Rydberg states
by pulsed electron impact has been studied by time-of-flight analysis.
Near the end of a 35-cm field-free flight path, the excited atoms pass
through a pair of electric field plates before entering an excited-atom
detector. Electric field ionization was...
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...
