Abstract We report on simultaneous magneto-optical trapping of fermionic 40K and
bosonic 87Rb atoms. This trap is the first step towards quantum degenerate fermi gas 40K. Laser lights for the two-species magneto-optical trap (MOT) are generated from diode lasers and tapered amplifier. The enriched 40K dispenser is utilized in the experimental setup. We obtain up to 107～108 40K and 108～109 87Rb atoms respectively in the steady-state single-species MOT.
