Abstract

We report on a dual species laser cooling apparatus capable of collecting over 108 Rb87 or Rb85 atoms from an atomic vapor or up to (8±2)×107 Li6 atoms directly into a magneto-optic trap (MOT) from an effusive oven without the need for a Zeeman slower. The use of a miniature atomic oven placed close to the trapping region yields a compact vacuum system with a captured flux of more than 4×106 lithium atoms per second and a high quality vacuum in the 1010  Torr range. The atomic sources, laser system, and vacuum system are described. In addition, we use this system to study atom loss from the MOT due to interspecies collisions between Li6 and Rb85 or Rb87. We report for the first time the heteronuclear loss coefficients for Li6Rb85 mixtures.
