Cooling and Trapping of Atoms and Particles

Abstract

We showed that it is possible to cool atoms in a one dimensional optical lattice using to a novel degenerate sideband cooling technique. This method was then extended to a three dimension optical lattice. With this method, we are able capture all the atoms in a MOT and directly cool them to the photon recoil temperature at phase space densities of 1/500 using low powered (20 mW) diode laser beams. This represents a 2 1/2 order of magnitude increase in phase space density over the best form of grey optical molasses.
