To obtain an ensemble with large OD, our experiment is based on an elongated 2D magneto-optical trap (MOT) of cesium atoms25,26,30. As sketched in Fig. 1a, the MOT relies on two pairs of rectangular-shaped coils and three retro-reflected trapping beams with a two-inch diameter and a total power of 350?mW. The resulting cigar-shaped ensemble has a length of 2.5?cm. The experiment cycle is completed with a repetition rate of 20?Hz (see Supplementary Note 1).
