Optical lattice
From Wikipedia, the free encyclopedia
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. This system of trapped atoms resembles a crystal in the sense that the atoms are localized periodically in space. | This atomic, molecular, and optical physics-related article is a stub.
