Spectroscopy and Manipulation of Single Atoms
HERBERT WALTHER
Abstract
In this paper recent experiments of our group performed with single atoms in cavities and traps are summarized. In the first part experiments with the one-atom maser are described dealing with the generation of number states of the photon field. In the second part of the paper spectroscopy of a single trapped In + ion is discussed being performed with the aim to realize a new frequency standard in the optical range.
