Abstract
An atomic oscillator includes a gas cell into which a metal atom and a buffer gas are sealed, a light source that emits light for exciting the metal atom in the gas cell, and a light detection unit (light reception unit) that detects the light which has been transmitted through the gas cell, in which the buffer gas includes neon (Ne) and argon (Ar), and a pressure ratio of Ar to the total of Ne and Ar is greater than 0 and less than 0.5.
Claims9
An atomic oscillator comprising:
- a gas cell into which a metal atom and a buffer gas are sealed;
- a light source that emits light for exciting the metal atom in the gas cell;
- and
- a light reception unit that detects the light which has been transmitted through the gas cell,
- wherein the buffer gas includes neon (Ne) and argon (Ar), and a pressure ratio of Ar to the total of Ne and Ar is greater than 0 and less than 0.5.
A frequency adjusting method of an atomic oscillator including a gas cell into which a metal atom, neon (Ne), and argon (Ar) are sealed, comprising:
- sealing a gas including Ne and Ar into the gas cell in a state in which a pressure ratio of Ar to the total of Ne and Ar is greater than 0 and less than 0.5.
