Laser cooling includes a number of techniques in which atomic and molecular samples are cooled down to near absolute zero.Laser cooling techniques rely on the fact that when an object (usually an atom) absorbs and re-emits a photon (a particle of light) its momentum changes.

Atom cooling trapping and quantum manipulation

With these respect, another relevant experiment has already demonstrated signi cant trapping times (˘ 28 ms) of single Cs atoms within a cavity, employing an additional far-o resonance trapping (FORT) mode [8]. atoms and were also responsible for the ﬁrst successful coherent splitting of a condensate on an atom chip; we will look at both these conﬁgurations. In section 3 we show how a second RF ﬁeld can be used both for characterising the potentials by spectroscopy and for carrying out evaporative cooling of adiabatically trapped atoms [8–10]. 2020-05-14 · Optical cooling is a unique technology aimed at cooling microscale targets, especially for atoms , ions , and nanoparticles . The optical forces acting on atoms can be coherent, as in the redistribution of the optical field, similar to optical tweezers, or incoherent, as in absorption and re-emission, which could not be observed from the trapping of dielectric particles [ 193 ].
