This doctoral thesis presents experiments on efficient laser cooling of fast stored 9Be+ ions to extreme phase-space densities. The dynamics of bunched cooling in different potentials and the important role of intra beam Coulomb scattering have been investigated on the basis of systematic measurements and realistic computer models. At extreme phase-space densities an abrupt disappearance of intra beam scattering is observed which could possibly indicate the onset of Coulomb ordering in the ion beam. Laser cooling of a coasting beam in an optical molasses is demonstrated. For the first time, true 3D laser cooling of a coasting beam has been realized.
