Abstract
An atomic oscillator includes: a gas cell which includes two window portions having a light transmissive property and in which metal atoms are sealed; a light emitting portion that emits excitation light to excite the metal atoms in the gas cell; a light detecting portion that detects the excitation light transmitted through the gas cell; a heater that generates heat; and a connection member that thermally connects the heater and each window portion of the gas cell to each other.
Claims12
A quantum interference device, comprising:
- a gas cell including two window portions having a light transmissive property and a side wall that seals metal atoms together with the two window portions;
- a light emitting portion that emits light that is transmitted through one of the window portions to excite the metal atoms;
- a light detecting portion that detects the light passing through the metal atoms and transmitted through the other window portion;
- a heating portion that generates heat;
- and
- a connection member that contains a material having a larger thermal conductivity than a material forming the side wall and that thermally connects the heating portion and each of the two window portions to each other.
