Laser cooling and trapping of neutral atoms*
In 1978, while I was a postdoctoral fellow at MIT, I read a paper by Art Ashkin (1978) in which he described how one might slow down an atomic beam of sodium using the radiation pressure of a laser beam tuned to an atomic resonance. After being slowed, the atoms would be captured in a trap consisting of focused laser beams, with the atomic motion being damped until the temperature of the atoms ...

This article presents a review 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.
متن کاملLaser Cooling and Trapping of Neutral Atoms
The ability to cool, manipulate, and trap atoms using laser light has allowed a new, rapidly expanding field to emerge. Current research focuses on improving existing cooling techniques, and the development of cold atoms as a source for applications ranging from atomic clocks to studies of quantum degeneracy. This review explains the basic mechanisms used in laser cooling and trapping, and illu...
متن کاملLaser cooling to quantum degeneracy.
We report on Bose-Einstein condensation in a gas of strontium atoms, using laser cooling as the only cooling mechanism. The condensate is formed within a sample that is continuously Doppler cooled to below 1 μK on a narrow-linewidth transition. The critical phase-space density for condensation is reached in a central region of the sample, in which atoms are rendered transparent for laser cooli...
متن کاملCooling and trapping Strontium atoms
We performed the simultaneous trapping of two isotopes (86Sr and 88Sr) in the red MOT (N.Poli et al. Phys. Rev. A 71, 061403(R) (2005)). Thanks to the low temperature obtained in the red MOT, such isotopic mixture is efficiently transferred into a FORT. We observe fast interspecies thermalization in the dipole trap which allows one to set a lower bound of 70aB on the 86Sr-88Sr elastic cross sec...
