Dalibard and Cohen-Tannoudji (1989) provided an el-egant quantum-mechanical treatment of simple model systems. They discussed two different types of cooling,
Introduction The purpose of this report is to present a survey of recent theoretical advances in the field of Laser Cooling and Trapping of Neutral Atoms and to point out a few general trends. The subsequent report, by Aspect, will cover the experimental developments. It is of course impossible, in a short time, to present an exhaustive review.
Abstract : In 1988, before the beginning of the current contract period, our group discovered that sodium atoms could be laser cooled well below the lower limit (the 'Doppler limit') predicted by the then generally accepted theory. Two main consequences of that discovery were a revamping of the theory of laser cooling and a renewed interest in the applications of laser cooling because of the ...
Laser cooling is the compression of the velocity distribution of an atomic sample (e.g., atomic beam) by momentum exchange with laser light [1,2]. It can be achieved by exploiting the Doppler shift to assure that fast atoms are decelerated more than slow ones [3,4]. It has been developed in part to ameliorate the effects of two distinct limits ...

From Ref. 21 Laser cooling and trapping of neutral atoms 43 providing the repumping light. For a 3.6 msec launch pulse, the atoms would scatter around 80 photons giving an initial velocity of 2.4 m/s and a fountain height of 30 cm. The atoms in the fountain were detected using a resonant photo-ionisation scheme.

A review is presented of some of the principal techniques of laser cooling and trapping that have been developed during the past 20 years. Its approach is primarily experimental, but its quantitative descriptions are consistent in notation with most of the theoretical literature. It begins with a simplified introduction to optical forces on atoms, including both cooling and trapping. Then its ...
The NBS-Gaithersburg experiments on laser deceleration and cooling of atomic beams are reviewed. The laser-cooling process is presented as an example of « lumino-refrigeration » by optical pumping originally proposed by Kastler. Prospects for using laser-cooled atoms in magnetostatic or radiative atom traps are discussed.

Abstract. Electromagnetic interactions can be used to act on atoms, to manipulate them, to control their various degrees of freedom. With the development of laser sources, this research field has considerably expanded during the last few years. Methods have been developed to trap atoms and to cool them to very low temperatures.

Finally, the eld of laser cooling and trapping received the 1997 Physics Nobel Prize in the persons of Steve Chu, Claude Cohen-Tannoudji and William Phillips [10]. It is possible to say that laser trapping and cooling is now part of the cannon of physics.

It enhances the density of atoms in phase space by many orders of magnitude reducing the need of large samples. These lecture notes review the fundamental principles of the eld and show some of the
