Research output: Contribution to journalArticlepeer-review


A two-species magneto-optical trap (MOT) for the simultaneous trapping of 40K and 87Rb was considered. Using a relatively simple four-color diode laser scheme and a single high-power semiconductor amplifier, atom numbers of NRB=2X109 and NK=1X107 were obtained. In addition, a pronounced number loss in the 40K MOT due to heteronuclear collisions in the presence of trapped 87Rb atoms was observed.
