Laser cooling Physical mechanisms and ultimate limits

  • Claude Cohen-Tannoudji
Conference paper


A review will be presented of various physical mechanisms allowing one to reduce the momentum spread δp of an ensemble of atoms to the lowest possible value. Emphasis will be put on recent developments which have led, in one, two and three dimensions, to values of δp well below the single photon momentum ħk. New theoretical approaches giving physical insight into the long time limit of these subrecoil cooling methods will be also described.
