Abstract :
Summary form only given. A coherent acceleration of atoms can be realized by an adiabatic sequence of Bragg reflections from an accelerating standing light wave. The arrangement of laser beams for such an acceleration is shown. The atom is illuminated by two counterpropagating laser beams. The fixed frequency of the pump laser /spl omega//sub 1/ is far detuned (/spl Delta/=/spl omega//sub 1/-/spl omega//sub 0/) from some allowed optical atomic transition having a frequency /spl omega//sub 0/. The frequency of the Stokes laser is linearly swept in time according to the law /spl omega//sub 2/(t)=/spl omega//sub 1/-/spl mu/t.
