Abstract
An atomic oscillator including a light source, a gas cell including an internal space in which alkali metal atoms are encapsulated, and a light detector that detects light which has emitted from the light source and has passed through the gas cell. The alkali metal atoms encapsulated in the internal space are adhered, in a liquid state or a solid state, to at least an incident window, such that light incident on the incident window is reduced.
Claims20
An atomic oscillator comprising:
- a light source;
- a gas cell including an internal space in which alkali metal atoms are encapsulated;
- and
- a light detector that detects light which has been emitted from the light source and has passed through the gas cell;
- wherein
- the gas cell includes an incident window through which the light from the light source is incident, an emission window through which the light is emitted to the light detector, and a side wall supporting the incident window and the emission window;
- the light incident on the incident window is reduced by the alkali metal atoms encapsulated in the internal space being adhered, in a liquid state or a solid state, to at least the incident window;
- and
- an amount of the alkali metal atoms that are adhered, in the liquid state or the solid state, to the incident window is larger than an amount of the alkali metal atoms that are adhered to the other surfaces.
