Webengaged in this area. The basic concepts of laser cooling and the most illuminating experiments are discussed. 1. Introduction In the past decade, laser control of atomic motion, which enables one to cool, trap, and channel atoms. has become a rapidly developing field of atomic-laser physics. WebAbstract. Recent developments in laser spectroscopy of atomic ions stored in electromagnetic traps are reviewed with emphasis on techniques that appear to hold the greatest promise of attaining extremely high resolution. Among these techniques are laser cooling and the use of single, isolated ions as experimental samples. thor being an alien https://leesguysandgals.com
