Phys. Rev. A 73, 011402(R) (2006) [4 pages]Simultaneous magneto-optical trapping of three atomic speciesWe report on the simultaneous trapping of two fermionic species, 6Li and 40K, and a bosonic species, 87Rb, demonstrating the first three-species magneto-optical trap ("triple MOT"). The apparatus including the atom sources and the three laser systems is described, and the single-species MOTs and the triple MOT are characterized. In triple MOT operation, typical atom numbers of 3.2×107 for 6Li, 1.5×107 for 40K, and 5.4×109 for 87Rb were achieved. Trap loss due to interspecies collisions was observed. We describe our way to optimize the triple MOT and turn it into a suitable source for the goal to achieve quantum degeneracy by evaporative and sympathetic cooling. ©2006 The American Physical Society
