Six-beam optical lattice with intrinsically stable time phases

Summary form only given.To manipulate atomic motion by laser radiation in two or three dimensions, atoms are usually exposed to several laser beams whose interference pattern results from the light-atom interaction and hence the atom dynamics. In general, the resulting light field crucially depends on the relative phases of the interfering light beams. One method to provide a laser field with a stable intensity and polarization configuration is to reduce the number of beams.
