Abstract
An atomic oscillator includes a gas cell having an internal space in which alkali metal atoms are entrapped, and a light output part that outputs excitation light containing a pair of resonance lights in resonance with the alkali metal atoms toward the internal space. Further, a width of the internal space along a direction perpendicular to an axis of the excitation light is W1, a width of the excitation light along the same direction in the internal space is W2, and a relation of 40%≦W2/W1≦95% is satisfied.

A quantum interference device comprising:
- a gas cell having an internal space in which metal atoms are entrapped;
- and
- a light output part that outputs light toward the internal space, the light containing a pair of resonance lights for resonance with the metal atoms,
- wherein a width of the internal space along a direction intersecting an axis of the light is W1,
- a width of the light along the intersecting direction in the internal space is W2, and
- 40%≦W2/W1≦95%.
A quantum interference device comprising:
- a gas cell having an internal space in which metal atoms are entrapped, the internal space having a width W1 in a first direction;
- and
- a light source emitting light toward the internal space for resonance with the metal atoms, the light having a width W2 in the first direction,
- wherein the first direction is orthogonal to a propagating direction of the light, and
- 40%≦W2/W1≦95%.
