      abstract     = {The generation of low surface roughness of the cut edge
                      during laser beam cutting is a challenge. The striation
                      pattern, which determines the surface roughness, can be
                      distinguished into regular and interrupted striations, the
                      latter resulting in an increased surface roughness. In order
                      to analyse their formation, the space- and time-resolved
                      cutting front geometry and melt film thickness were captured
                      during laser beam fusion cutting of aluminium sheets with a
                      framerate of 1000 Hz by means of high-speed synchrotron
                      X-ray imaging. The comparison of the contours of the cutting
                      fronts for a cut result with regular und interrupted
                      striations shows that the contour fluctuates significantly
                      more in case of interrupted striations. This leads to a
                      strong fluctuation of the local angle of incidence. In
                      addition, the average angle of incidence decreases, which
                      results in an increase of the average absorbed irradiance.
                      Both phenomena, local increase of absorbed irradiance and
                      its dynamic fluctuation, result in a local increase of the
                      melt film thickness at the cutting front which is
                      responsible for the formation of the interrupted
                      striations.},
