A dual-species magneto-optical trap for lithium and strontium atoms
Abstract
We present a machine built for experiments with ultracold mixtures of strontium and lithium atoms. The machine includes a science vacuum chamber and the relevant laser systems for cooling and trapping the atoms. With this machine, we realize a D2-line compressed magneto-optical trap (MOT) for 6Li and a narrow-linewidth 689-nm MOT for 84Sr, obtaining ~109 6Li atoms at 700 μK and ~107 84Sr atoms at 1.8 μK. Such a dual-species MOT provides an ideal starting point for realizing double degenerate mixtures of 6Li and Sr atoms.
