High resolution laser spectroscopy is a very precise method for investigations of the atomic structure, being sensitive to the smallest effects (e.g. relativity, QED). In order to challenge modern theory, few-electron ions are interesting because of their strong EM fields. These ions can be studied at heavy-ion facilties, such as GSI in Darmstadt, or IMP in Lanzhou, China. In order to create high charge states, the ions must be accelerated to almost the speed of light. Laser spectroscopy of e.g. fine structure transitions is then possible by exploiting the huge Doppler shift (anti-collinear laser). We report on results from experiments performed at the ESR (GSI) and the CSRe (IMP) storage rings, using C³⁺ and O⁵⁺ ion beams, respectively. Finally, we present our preparations for laser spectroscopy of Be-like krypton.
