Physical Review A

Laser cooling of a sodium atomic beam using the Stark effect

Abstract

A method of slowing and cooling a thermal sodium atomic beam using the Stark effect to hold the atoms in resonance during the slowing is described. A deceleration of the atoms down to 17 m/s could be experimentally achieved.

Laser cooling and electromagnetic trapping of neutral atoms

William D. Phillips, John V. Prodan, Harold J. Metcalf

Atoms in a thermal beam can be cooled, decelerated, and stopped using the radiation pressure from a nearly resonant laser beam. Several groups have already used this laser-cooling process on an atomic sodium beam. The techniques and results of the various experimental groups are reviewed, and applications of laser-cooled atoms, in particular the possibility of confining them in electromagnetic traps, are discussed.

Laser Preparation of a Monoenergetic Sodium Beam

A sodium atomic beam has been decelerated and cooled by a counterpropagating laser beam. Subsequently only these slow and cooled atoms with a temperature of less than 30 mK have been deflected up to an angle of 6°, using a part of the cooling laser beam. These atoms form a pure, well-defined and nearly monoenergetic slow atomic beam, as desired for many applications of cold atoms.

Resonance cooling of a sodium atomic beam using a time-modulated magnetic field

Zheng-Zhong Pan

Recently, there have been significant experimental advances in the laser cooling of a sodium atomic beam.1 Only three methods have been successful: (1) fixed frequency nonresonance cooling; (2) chirped frequency resonance cooling; and (3) spatial-varied magnetic-field Zeeman- tuned resonance cooling.

Large-angle beam deflection of a laser-cooled sodium beam

J. Nellessen, Jörg Helge Müller, K. Sengstock +1 more

A sodium atomic beam has been decelerated and laser cooled to a longitudinal beam temperature of less than 30 mK. Subsequently these slow atoms with a typical velocity of 100 m/sec were selectively deflected by laser-light forces. The deflection angle was typically 30°. The deflection scheme permits a stabilization of the transverse velocities in the deflected atomic beam down to the quantum-limit temperature for one dimension (0.7 × 240 μK). The experimentally achieved temperatures are of the order of 1 mK.

Laser Cooling of an Atomic Beam by Spatial Doppler Tuning of a Resonance Transition

Jun Umezu, Fujio Shimizu

Cooling of an atomic beam by Doppler tuning is proposed. The atomic beam is decelerated by repeatedly crossing a resonant laser beam at a decreasing angle. An example of the experimental configuration to slow down a two-level atomic beam by a factor of 20 using two lasers is given.
