Abstract
An atomic oscillator includes an atom cell, a first light source device, a second light source device, and a reception section. The atom cell is filled with alkali metal. The first light source device emits a light beam that includes a resonance light beam pair configured to be circularly polarized with each other in the same direction and configured to cause the alkali metal to resonate. The second light source device emits a light beam that includes adjustment light beam configured to be circularly polarized in a reverse direction to the resonance light beam pair. The reception device receives the resonance light beam pair that pass through the atom cell. The adjustment light beam may include the resonance light beam that causes the alkali metal to resonate. In addition, the resonance light beam pair may be a line and the adjustment light beam is a line.
