Simultaneous Magneto-Optical Trapping of Fermionic ⁴⁰K and Bosonic ⁸⁷Rb Atoms

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 10⁷～10^{8 40}K and 10⁸～10^{9 87}Rb atoms respectively in the steady-state single-species MOT.
