Abstract
High density samples of cold atoms have been obtained using an increasing-field Zeeman slower and a dark light trap. The Zeeman slower produces more than 1012 slow atoms/s. In the dark spontaneous-force light trap repulsive forces between atoms due to rescattered radiation are reduced because the atoms are confined predominantly in a “dark” hyperfine level that does not interact with the trapping light. In such a trap, more than 1010 sodium atoms have been trapped at densities approaching 1012 atoms cm−3.
