The dual frequency anisotropic Magneto-Optical Trap
The cloud of cold atoms produced by a Magneto-Optical Trap is known to exhibit instabilities. We examine in this paper in which limits it could be possible to realize an experimental trap similar to the configurations studied theoretically, i.e. mainly traps where one direction is privileged. We study the static behavior of an anisotropic trap, where anisotropy results essentially from the use ...
متن کاملTrap loss in a two-species Rb-Cs magneto-optical trap
During the past years, many experiments have been devoted to the study of excited-ground-state cold collisions using a sample of trapped cold atoms @1,2#. Recently, there has been greater interest in the study of collision mechanisms involving two different kinds of atoms in a mixed-species magneto-optical trap ~MOT! @3–9#. The nature of these collisions bears critically on matter-wave coherenc...
متن کاملMagneto Optical Trapping of Rb 87
Magneto optical traps brilliantly combine semi-classical optics with modern physics. By carefully controlling the polarization and frequency of laser beams, it is possible to trap and cool atoms down to the millikelvin range at a relatively low cost. This has opened previously inaccessible physical domains to enterprising physicists all around the world, and is responsible for some of the most ...
متن کاملStochastic dynamics of the magneto-optical trap
The cloud of cold atoms obtained from a magneto-optical trap is known to exhibit two types of instabilities in the regime of high atomic densities: stochastic instabilities and deterministic instabilities. In the present paper, the experimentally observed stochastic dynamics is described extensively. It is shown that it exists a variety of dynamical behaviors, which differ by the frequency comp...
متن کاملForbidden transitions in a magneto-optical trap.
We report the first observation of a nondipole transition in an ultracold atomic vapor. We excite the 3P-4P electric quadrupole (E2) transition in 23Na confined in a magneto-optical trap, and we demonstrate its application to high-resolution spectroscopy by making the first measurement of the hyperfine structure of the 4P(1/2) level and extracting the magnetic dipole constant A=30.6+/-0.1 MHz. ...
