Compact magneto-optical trap for rubidium atoms

P. L. Chapovsky

Abstract

The characteristics of a magneto-optical trap (MOT) using small-diameter cooling laser beams are considered. Trapping and cooling of Rb atoms from the surrounding gas of warm atoms takes place in the trap. A compact (140 μm) and stable atomic cloud is obtained with a density of 7 × 10 10 cm −3 , which is three orders of magnitude higher than the density of the surrounding gas.
