An inertial sensor includes a dual atom interferometer. A moving standing light wave generation device in the dual atom interferometer generates M (3≤M) moving standing light waves. Each of the M moving standing light waves is generated by a pair of counter-propagating laser beams. The moving standing light wave generation device adjusts two-photon detuning of a pair of counter-propagating laser beams corresponding to each of N (2≤N<M) moving standing light waves out of the M moving standing light waves such that the difference between an interferometric phase corresponding to one atomic beam obtained by interfering with the M moving standing light waves and an interferometric phase corresponding to the other atomic beam obtained by interfering with the M moving standing light waves stays constant.

An adjuster performs simultaneous irradiation of M laser beams to an atomic beam, where M is a predetermined integer satisfying 3≤M. The course of each of the M laser beams intersects with the course of the atomic beam. A component, in a direction perpendicular to the course of the atomic beam, of the sum of radiation pressure vectors that the M laser beams respectively have is zero. A component, in a direction of the course of the atomic beam, of the sum of the radiation pressure vectors that the M laser beams respectively have is negative for atoms having speeds greater than a predetermined speed, and positive for atoms having speeds smaller than the predetermined speed.

An atomic beam is irradiated with a first laser beam, a second laser beam, and a third laser beam. The first laser beam and the third laser beam each have a wavelength corresponding to a transition between a ground state and a first excited state. The second laser beam has a wavelength corresponding to a transition between the ground state and a second excited state. First, atoms each having a smaller velocity component than a predetermined velocity in a direction orthogonal to the traveling direction of the atomic beam are changed from the ground state to the first excited state by the first laser beam. Subsequently, a momentum is provided for individual atoms in the ground state by the second laser beam, which removes the atoms from the atomic beam. Finally, atoms in the first excited state are returned from the first excited state to the ground state by the third laser beam.
