Abstract:
An optical module of an atomic oscillator using a quantum interference effect includes a light source to generate first light including a fundamental wave having a center wavelength, and including a first sideband wave and a second sideband wave having wavelengths that are different from each other, a wavelength selection unit that emits second light by selecting the first sideband wave and the second sideband wave of the first light and by allowing them to pass through, a gas cell in which an alkali metal gas is sealed and to which the second light is irradiated, and a light detection unit that detects an intensity of the second light passing through the gas cell.
