(a) Geometry of the laser beams for RIR. (b) Scheme of atomic energy and momentum changes with different frequencies of probe beams for an atom with the mass M . Here, δ < 0 corresponds to a gain process for the probe beam and δ > 0 corresponds to an absorption process. The black circles symbolize populations of relevant energy states.
