The theory of laser cooling with anti-Stokes fluorescence is briefly … WebThe extension of laser cooling to neutral atoms was not easy. A basic problem was that no neutral atom traps could contain atoms with typical thermal energies. While ions could first be trapped and then laser-cooled, neutrals had to be laser cooled before they could be trapped. Laser cooling of free atoms is accomplished by directing a laser
