Phillips National Institute of Standards and Technology Gaithersburg, MD 20899 USA ABSTRACT: Radiative forces on atoms can be used both to cool the atoms to temperatures on the order of microkelvins and to trap them in a periodic array of microscopic potential wells formed by the interference of multiple laser beams, i.e., an optical Cooling of atoms in such a method takes place at the expense of a momentum loss by an atom during absorption of a plane light wave and re-emission of a spherical A magneto-optical trap is an apparatus which uses laser cooling and a spatially-varying magnetic field to create a trap which can produce samples of cold, trapped, neutral atoms. Temperatures achieved in a MOT can be as low as several microkelvin, depending on the atomic species, which is two or three times below the photon recoil limit.

Since then, it has been successfully implemented in two size ranges: the subnanometre scale, where light–matter mechanical coupling enables cooling of atoms, This chamber supports trapping, cooling, and manipulation of atomic clouds (Sect. 3.2.2). The two-chamber design allows for evaporation, preparation, and transport of the atoms while simultaneously maintaining the ultra-high vacuum in the science chamber. Laser cooling is primarily used to create ultracold atoms for experiments in quantum physics. These experiments are performed near absolute zero where unique quantum effects such as Bose–Einstein condensation can be observed.
