ATOMIC RESONANCE TRANSITION DEVICE, ATOMIC OSCILLATOR, ELECTRONIC APPARATUS, AND MOVING OBJECT

摘要

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.

1. An atomic resonance transition device comprising:
a cell having an internal space; a metal sealed within the internal space of the cell; a light emitter configured to emit light towards the metal, the light containing a resonance light pair configured to cause the metal to resonate; and a magnetic field applicator configured to apply a magnetic field to the metal, wherein the light diverges in a width direction in the internal space as the light travels from a light incident side of the cell toward a light exiting side of the cell, and the magnetic field has a portion in the internal space that increases in intensity in accordance with distance from the light incident side toward the light exiting side.
