      abstract     = {Laser polishing is an automated polishing solution by
                      remelting with laser radiation, which is also suitable for
                      polishing of complex freeform surfaces. Although first laser
                      polishing machine tools are available in the prototype stage
                      and the roughness achievable by laser polishing is
                      sufficient for many industrial applications, there is no
                      industrial implementation for laser polishing of 3D
                      components so far. The insufficient establishment of the
                      laser polishing process in the manufacturing or metalworking
                      industry is due, among other things, to the fact that the
                      laser polishing process is still too uneconomical. The
                      reason for this, apart from the high investment costs for a
                      laser polishing machine tool, is the area rate AR which is
                      too low for most applications. In the present work, three
                      different approaches for increasing the area rate AR in
                      laser polishing of steel materials are investigated for the
                      first time, with the aim of opening up a broader range of
                      applications for laser polishing for surfaces with medium
                      quality requirements (Ra=0.1-0.25 µm). By using a line-like
                      beam geometry and by adapting the process parameters for
                      pre-polishing as well as polishing pass, a more than tenfold
                      increase of the area rate AR compared to the state of the
                      art is achieved. In addition to the increase in the area
                      rate, the achievable roughness Ra for the three materials
                      investigated is also reduced, in some cases significantly,
                      by using line-like beam geometries.},
