Abstract.. We present a simple review of the basic physical processes allowing one to control, with laser beams, the velocity and the position of neutral atoms.. The control of the velocity corresponds to a cooling of atoms, that is, a reduction of the atomic velocity spread around a given value.. The control of the position means a trapping of ..
Although ion trapping, laser cooling of trapped ions, and trapped ion spectroscopy were known for many years [], it was only in 1985 that neutral atoms were first trapped [].. Such experiments offer the capability of the spectroscopic ideal of an isolated atom at rest, in the dark, available for interaction with electromagnetic field probes..
