Abstract
An atomic resonance transition device includes a gas cell having an internal space that seals an alkali metal, a light emitter that emits excitation light containing a resonance light pair that causes the alkali metal to resonate toward the alkali metal, and a magnetic field generator that applies a magnetic field to the alkali metal. The excitation light diverges in a width direction in the internal space as the light travels from a side where the excitation light is incident toward a side where the excitation light exits, and the magnetic field from the magnetic field generator has a portion where the intensity of the magnetic field increases in the internal space with distance from the side where the excitation light is incident toward the side where the excitation light exits.
