Abstract
Lossless polarization gradient cooling of 4 × 107 87Rb atoms in a far-detuned 2D optical lattice is demonstrated. Temperatures down to μK and phase space densities as high as 1 / 1000 are achieved in a total duty cycle of 215ms. It is shown that utilizing the vector component of the optical lattice allows lower temperatures to be achieved when compared with pure scalar lattices.
