In terms of observing relativistic effects and verifying the predictions of quantum electrodynamics, stored particles of high energy with a small momentum spread and small emittance are of great interest in current atomic physics and accelerator research. Due to its effectivity at high energies, laser cooling has proven to be a potentially powerful tool in recent years. Laser cooling is a longitudinal beam cooling method and is based on the resonant absorption and the subsequent spontaneous emission (fluorescence) of photons by ions [1]. We will show results of recent laser cooling experiments performed at the ESR at GSI Darmstadt, Germany [2]. [1] M. Bussmann, ICFA Beam Dyn. Newslett. 65 (2014). [2] D. Winters et al., Phys. Scr.
