Quantum interference device, atomic oscillator, and moving object

摘要

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.

主权项

1. A quantum interference device, comprising:
a gas cell including two windows having a light transmissive property and the gas cell sealing metal atoms therein; a substrate that is spaced apart from the gas cell, the substrate having a first surface and a second surface opposite to the first surface, the first surface facing one of the two windows; a light emitter that emits light, the light being transmitted through the two windows, the light emitter being provided on the first surface of the substrate; a heater that generates heat, the heater being provided on one of the first and second surfaces of the substrate, the heater and the light emitter being spaced part from each other; and a connection member that physically abuts the substrate and that transmits the heat from the heater to the two windows via the substrate without applying a current to the connection member.
