Abstract
We study the diffraction of a released sodium Bose-Einstein condensate by a pulsed standing light wave. The width of the momentum distribution of the diffracted atoms exhibits strong oscillations as a function of the pulse du ration, corresponding to periodic focusing and collimation of the condensat e inside the standing light wave. Applications of this thick grating regime of diffraction to atom interferometry are discussed.
