Abstract
An atomic oscillator includes a light source, a gas cell including an internal space in which an alkali metal atom is sealed, and a photodetector to detect light emitted from the light source and passing through the gas cell. A radiation region of the light source is wider than a sectional area of the internal space at a distal end of the gas cell relative to the light source.
