TEMPERATURE AND LOCALIZATION OF ATOMS IN 3-DIMENSIONAL OPTICAL LATTICES

We report temperature measurements of atoms trapped in a three-dimensi onal (3D) optical lattice, a well-defined laser-cooling situation that can be treated with currently available theoretical tools. We also ob tain fluorescence spectra from a 3D optical lattice, from which we obt ain quantitative information about the trapping atoms, including the o scillation frequencies, spatial localization, and a temperature, which is in good agreement with our direct measurements. For comparison we study a 1D lattice using the same atom (cesium).
