Magneto-Optical Trap of Cesium Atoms

We have trapped a cold sample of cesium atoms in a magneto-optical trap. The damped harmonic force of magneto-optical trap was used to capture and trap the cesium atoms directly from a room temperature vapor. About 1.5 x 10⁷ cesium atoms with a density of 3 x 10⁹ atoms/cm³ formed a 4mm³ cesium atomic cloud with temperature below 500μK.
