Zusammenfassung

We present a recently established setup for laser spectroscopy at CRYRING@ESR at the GSI Helmholtz Centre for Heavy Ion Research. Here, laser spectroscopy can be performed on stored and cooled ion bunches and coasting beams. First spectra of  24,25Mg+ ions are presented that were recorded by classical Doppler-limited fluorescence spectroscopy as well as Λ-spectroscopy using counter- and copropagating laser beams that are Doppler-shifted by several nm.
