A proposal for laser cooling antihydrogen atoms
We present a scheme for laser cooling applicable to an extremely dilute sample of magnetically trapped antihydrogen atoms (H̄). Exploiting and controlling the dynamical coupling between the H̄’s motional degrees of freedom in a magnetic trap, three-dimensional cooling can be achieved from Doppler cooling in one dimension using the 1s1/2 − 2p3/2 transition. The lack of three-dimensional access to ...
متن کاملLaser cooling of atoms
The concept of radiation-pressure cooling of atoms was independently suggested in 1975 for the case of a gas of neutral atoms by Hänsch and Schawlow, and for atomic ions bound in an electromagnetic trap by Wineland and Dehmelt. While the notion that momentum exchange from a photon moving in the opposite direction could slow an individual atom was well understood, until this time no one had come...
متن کاملLaser cooling and trapping of atoms
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 t...
متن کاملLaser 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 ...
