Light induced atom desorption:a photo-atomic effect

The effect of non resonant and weak light on the adsorption-desorption processes of alkali atoms on organic coated surfaces is discussed and a new phenomenon, the light-induced atom desorption, is presented. It is demonstrated that light can control the adsorption-desorption as well as the diffusion of the atoms inside silane coatings

White-light laser cooling of ions in a storage ring

We propose the use of a "white laser" for laser cooling of ions in a storage ring. The use of a broad-band laser provides a radiation pressure force with wide velocity capture range and high magnitude, which is promising to improve the performance of both longitudinal and indirect transverse cooling. This wide-range force could also be suitable for direct transverse cooling of low-density beams
