Recent experiments at the Experimental Storage Ring (ESR) at GSI have shown that relativistic Li-like carbon (C3+) ion beams can be laser-cooled to an un-precedented momentum spread of Δp/p ≈ 10-7. Here, a single-frequency laser was tuned to the Doppler-shifted 1s22s → 1s22p (2P1/2 and 2P3/2) transitions. These results encourage the application of laser cooling to beams of other Li- and Na-like ions at even higher energies, as will e.g. be available at FAIR.
