One of the most promising techniques for ion beam cooling at relativistic energies, is laser cooling. The fluorescence emitted after laser excitation 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. The cooling transition in the ions was excited using a pulsed laser system with a high repetition rate, and a wide-scanning cw laser system. A novel XUV detector system, installed inside the vacuum of the ESR, was used to detect the fluorescence from the ions. We will present the experimental setup and preliminary data, and give an outlook on future experiments at FAIR in Germany and HIAF in China.
