Atomic resonance transition device, atomic oscillator, clock, electronic device and moving body

摘要

An atomic resonance transition device includes an atomic cell in which an atom is sealed, a first light source part to emit a first light resonant with a D1 line of the atom in the atomic cell, a second light source part 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 in the atomic cell, and a detection part 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.
