Claim Text:
1. An atomic resonance transition device, comprising: an atomic cell in which an atom is sealed; a first light source that is configured to emit a first light resonant with a D1 line of the atom; a second light source that is configured to emit a second light having a wavelength different from that of the first light and resonant with the D1 line or a D2 line of the atom; a detector that is configured to detect a light beat due to interference between the first light and the second light passing through the atomic cell and to generate a beat signal; a first controller that is configured to control the first light source and causes the wavelength of the first light to become a peak wavelength of an absorption spectrum of the atom; and a second controller that is configured to control the second light source and causes the wavelength of the second light to become the peak wavelength of the absorption spectrum of the atom.
