All-Optical Realization of an Atom Laser
arXiv:cond-mat/0307620 · doi:10.1103/PhysRevLett.91.240408
Abstract
We demonstrate an atom laser using all-optical techniques. A Bose-Einstein condensate of rubidium atoms is created by direct evaporative cooling in a quasistatic dipole trap realized with a single, tightly focused CO-laser beam. An applied magnetic field gradient allows formation of the condensate in a field-insensitive spin projection only, which suppresses fluctuations of the chemical potential from stray magnetic fields. A collimated and monoenergetic beam of atoms is extracted from the Bose-Einstein condensate by continuously lowering the dipole trapping potential in a controlled way to form a novel type of atom laser.
