Аннотация

We provide a comprehensive study of atomic Raman and Bragg diffraction when coupling to a pair of counter-propagating light gratings (double diffraction) or to a single one (single diffraction) and discuss the transition from one case to the other in a retro-reflective geometry as the Doppler detuning changes. In contrast to single diffraction, double Raman loses its advantage of high diffraction efficiency for short pulses and has to be performed in a Bragg-type regime. Moreover, the structure of double diffraction leads to further limitations for broad momentum distributions on the efficiency of mirror pulses, making the use of ultra-cold ensembles essential for high diffraction efficiency.
