Abstract
We report the experimental realization of new stable three-dimensional schemes for trapping neutral cesium atoms in a vapor cell that use either two or four Gaussian laser beams. Probe-beam absorption is employed to characterize both types of trap, and densities of 2 × 108 and 1 × 1010 cm-3, respectively, are measured for the two-and four-beam traps. The two-beam trapping mechanism combines a longitudinal magneto-optical force with a transverse spontaneous radiation pressure force associated basically with the beam geometry. This theoretical analysis compares well with our experimental observations.
