Optical lattice

An optical lattice is formed by using counterpropagating laser beams to create a periodic (in space) intensity pattern. The resulting periodic potential can then be used to trap neutral atoms via the Stark shift. Atoms are cooled and localized in the potential minima. The resulting system of trapped atoms resembles a crystal in the sense that the atoms are localized periodically in space.
