Bragg transitions of a two-level atom in the field of two pairs of counter-propagating light pulses with different carrier frequencies have been studied theoretically. Bragg transitions are treated as coherent multiphoton diffraction processes, in which, under an appropriate tuning to the Bragg resonance, the atomic momentum can change by 2nhk in a single scattering event, whereas single-photon transitions are suppressed due to a large detuning from the resonance. It has been shown that in this configuration, the transition efficiency is practically independent of the pulse area, in contrast to the case of a single pair of pulses. The physical basis of this effect consists in an almost adiabatic interaction of the atom with the field, similarly to the interaction with temporally overlapping counter-propagating pulses with off-resonant carrier frequencies [V.I. Romanenko, L.P. Yatsenko. Zh. Eksp. Teor. Fiz. 117, 467 (2000); V.I. Romanenko, L.P. Yatsenko. JETP 90, 407 (2000)]. The possibility of the momentum splitting of an atomic beam, which is robust with respect to variations of light intensity, and of the formation of selective laser mirrors has also been demonstrated. The proposed approach to control atomic motion can be applied to the study of interference phenomena in atomic optics.
