  "textContent": "A device comprises thermal atomic source(s), atom interference lasers, and additional laser beam(s). The thermal atomic source(s) provide atomic beam(s). The atom interference lasers are disposed to provide interrogation laser beams that interrogate the atomic beam(s) to assist in generating atom interference. The interrogation laser beams are configured so as to enable a first speed selectivity and/or angle selectivity of a set of atoms used in the atom interference by restricting the set of atoms. The additional laser beam(s) are configured in such a way that, combined with the speed and/or the angle selectivity of the atom interference lasers, achieve a second speed selectivity and/or angle selectivity of the set of atoms that contribute to a final detected interference signal by restricting the set of atoms to a second speed-angle phase space, where the first speed-angle phase space and the second speed-angle phase space intersect to enhance signal stability.",
