Modern laser systems are powerful tools for laser cooling and laser spectroscopy of
stored relativistic ion beams. Although the laser photons interact with the electronic
structure of the ions only, thereby achieving a precision high enough to even infer
QED effects, spectroscopic information from the ionic structure may also reveal some
properties of the nuclei (e.g. nuclear charge radius, nuclear magnetic moment).
Therefore, it is very important to connect these novel laser systems to accelerators
via proper laser beamlines and transport the laser light either through air or through
vacuum. During my OCPC postdoc at GSI and HI-Jena, I have worked on three
different laser beamlines, and I have organized my talk accordingly. Firstly, I will
present the vacuum UV laser beamline for the SIS100 and will highlight the
importance of control over the polarization of the laser light. Secondly, I will show and
discuss the vacuum laser beamline for the connection between a novel tabletop XUV
light source and the CRYRING storage ring, which will e.g. support laser ionization of
C+ ions. Last but not least, I will inform about the recent laser spectroscopy test
experiment at the ESR storage ring, which used modern pulsed UV laser systems and
XUV light detection (in vacuum) to try to determine the (1s22s2p)3P0–3P1 level
splitting in Be-like krypton (86Kr32+).
