Laser-cooled
WebCommon laser-cooling configurations include optical molasses, the magneto-optical trap, and the Zeeman slower. Atomic ions, trapped in an ion trap, can be cooled with a single laser beam as long as that beam has a component along all three motional degrees of freedom. This is in contrast to the six beams required to trap neutral atoms.
