source will be created and delivered to GSI for first experiments that will be conducted at the ESR. A joint collaboration with the Atomic-Physics group at GSI and the groups of Prof. Nörtershäuser and [...] below. Laser spectroscopy of highly charged ions and exotic atoms is an important part of the current GSI atomic physics research program, and will be extended by the considerable advantages of FAIR. This [...] experience in the realization of widely-tunable diode lasers and solid state lasers. They have, for example, development a fast tunable cw-laser system with a broad tuning range, which was successfully used
