  • An optical lattice clock is an atomic clock proposed in 2001 by Hidetoshi Katori, one of the inventors of this application.
  • Optical lattice clocks confine a group of atoms within an optical lattice formed by laser light and measure the resonant frequency in the visible light range, making it possible to measure with an accuracy of 18 digits, far exceeding the accuracy of current cesium clocks. It is.
  • Optical lattice clocks are being actively researched and developed by a group of inventors, and are also being researched and developed by various domestic and international groups, and are being developed as next-generation atomic clocks.
  • Patent Document 1 describes forming a one-dimensional moving optical grating inside an optical waveguide having a hollow passage.
  • Patent Document 2 describes a mode of setting an effective magic frequency. In fact, magic wavelengths have been determined theoretically and experimentally for strontium, ytterbium, mercury, cadmium, magnesium, etc.
  • Patent Document 3 describes a radiation shield that reduces the influence of blackbody radiation radiated from surrounding walls.
  • Optical lattice clocks measure time with high precision, so it is possible to detect a difference in altitude of 1 cm above the earth based on the general relativity effect of gravity as a deviation in the way time progresses. Therefore, if optical lattice clocks can be miniaturized and made portable so that they can be used in the field outside of the laboratory, the possibility of application to new geodetic technologies such as underground resource exploration, underground cavity detection, and magma chamber detection will expand. By mass-producing optical lattice clocks and placing them in various locations to continuously monitor temporal fluctuations in gravitational potential, applications such as detecting crustal deformation and spatial mapping of gravitational fields will become possible. In this way, optical lattice clocks are expected to go beyond high-precision time measurement and contribute to society as a new fundamental technology.

  • the frequency of the laser beam is set to a value that is negatively tuned from the resonance frequency of the atoms.
  • momentum of the photons is imparted to the atoms, which acts as radiation pressure on the atoms.
  • the frequency of the laser light that opposes the movement undergoes a Doppler shift so that it approaches the resonance frequency of the atom.
  • the frequency of the laser light parallel to the direction of its motion undergoes a Doppler shift away from the resonance frequency of the atoms. Therefore, the atoms experience more radiation pressure from the laser light that opposes their motion, and as a result they slow down.
