Abstract

We demonstrate the production of high-density cold <sup>87</sup>Rb samples (2×10<sup>14</sup>atoms/cm<sup>3</sup>) in a simple optical lattice formed with YAG light that is diffracted from a holographic phase plate. A loading protocol is described that results in 10,000 atoms per 10µm×10µm×100µm unit cell of the lattice site. Rapid free evaporation leads to a temperature of 50µK and phase space densities of 1/150 within 50 ms. The resulting small, high-density atomic clouds are very attractive for a number of experiments, including ultracold Rydberg atom physics.
