Abstract:
Method and apparatus for producing a cooled atom beam suitable for use applications requiring cold atoms. A two-stage cooling process is employed in which the atoms in the atom beam are cooled in two, spatially separated regions of a cooling apparatus, wherein the atoms are first cooled in two dimensions by two counterpropagating laser beams under a magnetic field and then are cooled in three dimensions by means of an optical molasses, where the power, frequency, and magnetic fields are tuned to obtain a continuous beam of three-dimensionally cooled atoms having a controllable velocity distribution, very low decoherence, and low background atomic gas loss.
