Abstract: An electronic state splitter for atoms comprises an atom supplier, an atom movement path, a probe laser source, and a magnetic field generator. The atom supplier supplies atoms moving at a constant velocity along the atom movement path. The probe laser source supplies a probe laser propagating in the atom movement path in the same direction as or opposite to the motion of the atoms on the same axis as the atom movement path. The magnetic field generator generates a magnetic field orthogonal to the atom movement path in the atom movement path to mix the wave function of the clock upper state with the electronic state allowing electric dipole transitions, allowing pulsed excitation of clock transitions by the probe laser uniform in time and space. Accordingly, continuous spectroscopy of atomic transitions and frequency control of the probe laser are possible, which improves the stability of the atomic clock.
