Abstract

A laser-cooled neutral-atom beam from a low-velocity intense source is split into two beams while it is guided by a magnetic-field potential. We generate our multimode beam-splitter potential with two current-carrying wires upon a glass substrate combined with an external transverse bias field. The atoms are guided around curves and a beam-splitter region within a 10-cm guide length. We achieve a maximum integrated flux of 1.5×105atoms/s with a current density of 5×104amp/cm 2 in the 100-µm -diameter wires. The initial beam can be split into two beams with a 50/50 splitting ratio.
