<p>An optical module for an atomic oscillator using a quantum interference effect includes a light source adapted to emit a light including a fundamental wave having a predetermined wavelength, and sideband waves of the fundamental wave, a wavelength selection section to which the light from the light source is input, and adopted to transmit the sideband waves, a gas cell encapsulating an alkali metal gas, and irradiated with a light transmitted through the wavelength selection section, and a light detection section adapted to detect intensity of a light transmitted through the gas cell, and the wavelength selection section includes an optical filter section adapted to transmit a light having a wavelength within a predetermined wavelength range, and an optical filter characteristic control section adapted to vary the wavelength range of a light to be transmitted by the optical filter section.</p> |
