Raman-Nath approximation for atom diffraction in the laser field of counterpropagating waves: instantaneous turn-on of interaction
Lilit A. Hovhannisyan, A. Zh. Muradyan
The problem of Kapitza-Dirac diffraction is solved in the Raman-Nath approximation without limitations on resonance detuning. A formula for the scattering amplitude in a definite integral form is obtained. It shows that in the case of initial superposition state of discrete Gaussian form the scattering spectrum has a new regularity, more usable for atomic optics.
