Abstract
An atomic oscillator includes: an atomic cell in which an alkali metal is sealed; a light-emitting element that emits light to be radiated to the atomic cell; a light-receiving element that detects the light transmitted through the atomic cell; a first optical element that has light transmittance and is disposed between the atomic cell and the light-emitting element; and a second optical element that has light transmittance and is disposed between the first optical element and the atomic cell. The first optical element reflects the light from the light-emitting element toward the light-emitting element in a first direction inclined with respect to an optical axis of the light. The second optical element reflects the light from the light-emitting element toward the light-emitting element in a second direction inclined in a direction different from the first direction with respect to the optical axis of the light.
