Abstract
An atomic oscillator, attention is paid to the fact that the degree of change of the energy difference between the two ground levels of the alkali metal atom with respect to the change of the magnetic field intensity is specific to each of the magnetic quantum numbers, a resonant light pair to cause a transition between the two ground levels corresponding to each of the plural magnetic quantum numbers is sequentially generated, plural pieces of profile information capable of specifying the energy difference between the two ground levels corresponding to each of the magnetic quantum numbers are sequentially acquired based on the detection signal, the change amount of the magnetic field intensity is specified based on the acquired plural pieces of profile information, and the control is performed so that the intensity of the magnetic field becomes constant.
