Abstract
We trap and cool a gas composed of 40K and 87 Rb, using a two-species magneto-optical trap (MOT). This trap represents the first step towards cooling the Bose-Fermi mixture to quantum degeneracy. Laser light for the MOT is derived from laser diodes and amplified with a single high-power semiconductor amplifier chip. The four-color laser system is described, and the single-species and two-species MOTs are characterized. Atom number of 1 X 10740K and 2 X 10987Rb are trapped in the two-species MOT. Observations of trap loss due to collisions between species is presented and future propects for the experiment are discussed.Citation
