|Dipole potentials are applied to mani-pulate cold atoms and to create atom optics components. Specific potential forms are obtained with laser beams, whose intensity profile is shaped by using a spatial light modulator.
|Atomic prism/biprism: the prism/biprism effect is generated with a triangular dipole potential. The deviation depends on the triangle slope and the pulse duration.
Achromatic atomic lens: to get an achromatic lens, the applied potential is parabolic. The sequence can include one or several laser pulses. The pulse durations and the intervals determine the magnification obtained by such an atomic lens.
