Abstract:
     The invention provides a method and device for improving performance of micro atomic beam optical frequency atomic clock, belonging to the field of optical frequency- range frequency standard technique and the method comprises: adding a laser corresponding to a strong transition line, relative to the transition energy level of the atomic clock, for atom detection; after atoms move to the detecting region and act with the added laser, each atom emits hundreds of spontaneous radiating photons to be detected by a photoelectric accepting system. Because of using energy level conversion detecting method, i.e. using the added laser for detection, it raises original atom detection efficiency by much, thus assuring each atom needing to be detected can be detected.
