Compact magneto-optical trap for rubidium atoms

Compact magneto-optical trap for rubidium atoms

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 {mu}m) and stable atomic cloud is obtained with a density of 7 x 10{sup 10} cm{...

Zusammenfassung: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 {mu}m) and stable atomic cloud is obtained with a density of 7 x 10{sup 10} cm{sup -3}, which is three orders of magnitude higher than the density of the surrounding gas.
