We observed guiding, collimating, focusing, and splitting of a continuous, low-velocity rubidium atomic beam with a blue-detuned dark-hollow laser beam. The low-velocity atomic beam was produced in a magneto-optical trap and was loaded into the dark center of the hollow beam. By overlapping the dark-hollow beam with the atomic beam, the rubidium atoms could be collimated or focused. When the dark-hollow beam intercepted the atomic beam at an angle, two spatially separated rubidium atomic beams were produced, one of which was extracted and guided by the dark-hollow beam.
