Atom Cooling and Trapping. Now I'm just getting started on this page, but here is a brief explanation of one process we will employ to cool our Rubidium vapor. This primary process is called Optical Molasses. Below is an diagram of Optical Molasses. Read the explantion below the diagram for an explanation of the process.

In later proposals, laser trapping , a variant of cooling which requires both scattering and a dipole force, would be introduced.

Atom Cooling and Trapping. Now I'm just getting started on this page, but here is a brief explanation of one process we will employ to cool our Rubidium vapor.

May 1998; Physical Review A This configuration gives rise to atom cooling in the transverse plane via a Sisyphus cooling mechanism similar to the one The striking advances along these lines have been recognized by awards of Nobel prizes to 21 individuals in this area; most recently, the 1997 Nobel prize was given for laser cooling and trapping of neutral atoms (Phys. Today, 1997). We demonstrate the possibility of three-dimensional cooling of neutral atoms by illuminating them with two counterpropagating laser beams of mutually orthogonal linear polarization, where one of the lasers is a speckle field, i.e., a highly disordered but stationary coherent light field. This configuration gives rise to atom cooling in the transverse plane via a Sisyphus cooling mechanism Neutral atoms and ions can now be cooled, trapped, and precisely manipulated using laser beams and other electromagnetic fields. This has made it possible to control external degrees of freedom at the quantum level, thereby making possible a variety of interesting new physics.

This paper introduces and reviews light forces, atom cooling and atom trapping.

These early proposals for laser cooling only relied on "scattering force", the name for the radiation pressure. In later proposals, laser trapping , a variant of cooling which requires both scattering and a dipole force, would be introduced. The striking advances along these lines have been recognized by awards of Nobel prizes to 21 individuals in this area; most recently, the 1997 Nobel prize was given for laser cooling and trapping of neutral atoms (Phys. Today, 1997).
