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.

An optical module of an atomic oscillator using a quantum interference effect, comprising:
- a light source generating first light, the first light including a fundamental wave having a center wavelength, and the first light including a first sideband wave and a second sideband wave, the first and second sideband waves 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 therethrough while reducing or eliminating the fundamental wave;
- 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.
