High-power laser cutting is extensively used in many industrial applications. An important weakness of this process is the formation of striations (regular lines on the cut surface), which affect the quality of the surfaces produced. The elimination of striation is thus of considerable importance, since it could open up a variety of novel high-precision applications. This study presents the results of laser cutting of EN 43 mild steel sheets using a high power fibre laser. Striation-free laser cuts are demonstrated for cutting 1 and 2 mm thick mild steel sheets. The optimal operating windows are presented
