摘要： A quantum interference device causing electromagnetically induced transparency in an alkali metal atom includes: a light source generating first and second resonant lights with frequency differences Δω; a magnetic field generator applying a magnetic field to the atom; a light detector detecting intensities of the first and second resonant lights passing through the atom; and a controller causing a frequency difference between specified first and second resonant lights to equal a frequency difference corresponding to an energy difference between two ground levels of the atom based on the detected light. The controller causes the frequency Δω or magnetic field intensity to satisfy 2×δ×n=Δω or Δω×n=2×δ. The frequency δ corresponds to an energy difference between two Zeeman split levels differentiated by one magnetic quantum number and generated in the two ground levels of the atom by energy splitting.

摘要： A method of controlling an atomic oscillator includes generating a resonant light pair in response to a center frequency signal and a sideband signal, and setting the sideband signal so that an electromagnetically induced transparency (EIT) phenomenon does not occur in a gas cell of the atomic oscillator. The method includes applying the resonant light pair to the gas cell and detecting an intensity level of light transmitted through the gas cell. While the sideband signal is set so that the EIT phenomenon is not occurring, the center frequency signal is varied until a minimum value of the intensity level is identified. A first frequency is calculated by subtracting a predetermined frequency offset from the center frequency at which the intensity level was equal to the minimum value. A center frequency of the resonant light pair is set to the first frequency for operation of the atomic oscillator.
