Production Of Multiple 87Rb Condensates And Atom Lasers By Rf Coupling
  We have investigated the rf output coupling of a 87Rb condensate from a Ioffe-Pritchard magnetic trap. Multiple condensates in different Zeeman states are produced, their population being varied by playing with the duration and the amplitude of the rf pulse. Both pulsed and continuous outputs (atom laser) have been observed.
