Abstract

The invention provides an optical module for atomic oscillator and an atomic oscillator. An optical module for an atomic oscillator by using a quantum interference effect includes a light source part to emit resonant light having two different wavelengths, a gas cell in which an alkali metal atom gas is enclosed and to which the resonant light is irradiated, a light detection part to detect an intensity of the resonant light transmitted through the gas cell, and a gas-flow generation part to generate a flow of the alkali metal atom gas.

Description

technical field

[0001] The present invention relates to an optical module for an atomic oscillator and an atomic oscillator. Background technique

[0002] In recent years, atomic oscillators using CPT (Coherent Population Trapping), which is one of the quantum interference effects, have been proposed, and miniaturization and low power consumption of devices are expected. The atomic oscillator using CPT is an oscillation that utilizes the phenomenon (EIT phenomenon: Electromagnetically Induced Transparency: Electromagnetically Induced Transparency: Electromagnetically Induced Transparency: Electromagnetically Induced Transparency) that stops the absorption of coherent light when alkali metal atoms are irradiated with coherent light having two different wavelengths (frequency). device.

[0003] In an atomic oscillator, an alkali metal atom such as rubidium (Rb) or cesium (Cs) is usually enclosed in a container (gas cell) made of silicon oxide or the like, and the EIT phenomen...
