Laser cooling is one of the most promising techniques for ion beam cooling at high energies. The fluorescence emitted during the cooling process can be used for both optical beam diagnostics and precision spectroscopy. We present results on experiments with 12C3+ beams (122 MeV/u) stored in the experimental storage ring (ESR) in Darmstadt, Germany. For the excitation of the cooling transition, a pulsed laser system with a high repetition rate and a wide-scanning cw laser system have been used simultaeneously. For the fluorescence detection a novel XUV detector system installed inside the vacuum of the ESR. We will discuss the experimental setup and preliminary data on the interaction of the lasers with the beam and discuss them in the light of applications at future high energy storage rings at FAIR and HIAF.
