Abstract
The specific environment of a storage ring for fast ions offers new possibilities for stimulated laser cooling based on transient optical effects, like optical pi-pulses or the rapid adiabatic passage.[1] By the application of electro static potentials to the stored ion beam, the ion velocity and thus, as a consequence of the Doppler effect, the laser frequency seen by the ions in their rest frame can be changed locally in a well-defined manner. In this way, it is quite easy to realize an alternating or pulsed optical interaction of the stored ions with intense cw laser beams co- and counterpropagating with the ion beam. In an appropriate scheme, this can lead to a stimulated transfer of photons from one laser beam to the other and thus to a stimulated optical force exerted on the ions.
