Abstract
An optical module for an atomic oscillator 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.
