Laser cooling and trapping is the ability to cool atoms down to unprecedented kinetic temperatures, and to confine and support isolated atoms in “atom traps”. This unique new level of control of atomic motion allows researchers to study the behavior of atoms and quantum mechanical properties. 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.
Recent Evaporative cooling works on the principle that, following confinement of the atoms in a magneto-optical trap, the lowering of the sides of the potential well (in The ability to cool, manipulate, and trap atoms using laser light has allowed a new, rapidly expanding field to emerge.

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.

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. 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). Laser Cooling and Trapping 1 INTRODUCTION Laser cooling and trapping of neutral atoms is a rapidly maturing and yet still expanding area of physics research that has seen dramatic new developments over the two decades.

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. The emphasis is on the physics of the basic processes. In discussing conservative forces the semi-classical dressed states are used rather than the usual quantized field dressed states. Atom loss can be calculated from the evolution of phase-space distribution function W(q,p,t) through FPE with two boundary conditions, W(q,p= 2MU 0,t)=0 and W(q,p=0,t)=0, where U 0 is the maximum kinetic energy the cooling and trapping process can capture.

To honor OSA's centennial, JOSA B Centennial Editor Prem Kumar selected articles from a variety of topic areas that reflect the progression of each area over the journal's history.The figure shows a
It has been roughly three decades since laser cooling techniques produced ultracold atoms, leading to rapid advances in a wide array of fields. Until recently
For example, such an atomic sample has an energy width comparable to the capture range of optical molasses or the well depth of a neutral atom trap (see below). 1 INTRODUCTION.

Laser Cooling and Trapping 1 INTRODUCTION Laser cooling and trapping of neutral atoms is a rapidly maturing and yet still expanding area of physics research that has seen dramatic new developments over the two decades. These include the ability to cool atoms down to unprecedented kinetic temperatures (well below single photon recoil atoms would be captured in a trap consisting of focused laser beams, with the atomic motion being damped until the temperature of the atoms reached the microkelvin range.
