Phys. Rev. Lett. 85, 5543–5546 (2000)Cold Atom Beam Splitter Realized with Two Crossing Dipole GuidesReceived 9 May 2000; published in the issue dated 25 December 2000 Cold rubidium atoms, coupled and guided in a vertical laser beam by the dipole force, have been split into two atomic beams, by using a second time-dependent laser beam crossing the vertical one at a 0.12 rad angle. Transfer efficiency as large as 40% has been obtained. At 10 mm below the cold atom source, the two atomic beams have a few hundred micron size and are more than one millimeter apart from each other. © 2000 The American Physical Society URL:
