Webcollective dynamics in a non-interacting atomic gas inside an optical cavity. We then propose to utilise this expectation value to enhance the laser cooling of many atoms … WebAbstract. Recent developments in laser spectroscopy of atomic ions stored in electromagnetic traps are reviewed with emphasis on techniques that appear to hold the greatest promise of attaining extremely high resolution. Among these techniques are laser cooling and the use of single, isolated ions as experimental samples.
WebEvaporative cooling is an atomic physics technique to achieve high phase space densities which optical cooling techniques alone typically can not reach.. Atoms trapped in optical or magnetic traps can be evaporatively cooled via two primary mechanisms, usually specific to the type of trap in question: in magnetic traps, radiofrequency (RF) fields are used to … Webcollective dynamics in a non-interacting atomic gas inside an optical cavity. We then propose to utilise this expectation value to enhance the laser cooling of many atoms through a cyclic two-stage process which consists of cooling and displacement stages. During cooling stages, short laser pulses are applied.
WebOct 22, 2014 · We show that by a suciently slow repumping process, one can avoid the problems of reabsorptions in laser cooling of trapped atoms, even in the case of … WebThe extension of laser cooling to neutral atoms was not easy. A basic problem was that no neutral atom traps could contain atoms with typical thermal energies. While ions could first be trapped and then laser-cooled, neutrals had to be laser cooled before they could be trapped. Laser cooling of free atoms is accomplished by directing a laser
