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.
