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. To excite the cooling transition, a pulsed laser system with a high repetition rate, and a wide-scanning cw laser system have been used. To detect the fluorescence, a novel XUV detector system, installed inside the vacuum of the ESR, was used. We will present the experimental setup and preliminary data on the interaction of the lasers with the ion beam, and discuss it in the light of future experiments at the high-energy storage rings of FAIR in Germany and HIAF in China.
