Description

technical field [0001] The invention relates to an optical lattice, especially a two-way controllable one-dimensional optical lattice device, which is used for precision measurement and quantum information control using cold atoms as a medium, and belongs to nonlinear laser spectroscopy technology, precision laser spectroscopy technology field. Background technique [0002] At present, optical lattices have become the standard devices for cold atomic optical frequency standards and quantum simulation research. Ultra-precise spectra that eliminate atomic motion and collision effects can be obtained in an optical lattice, thus providing a highly stable external reference frequency. This technique has been applied in optical frequency standard. Optical lattices are also widely used in research fields such as quantum simulation. Since the realization of atomic gas Bose-Einstein condensate in 1995, people have used cold atoms and quantum degenerate Bose (or Fermi) atomic gases ...
