Abstract (en)
[origin: WO2021122100A1] A laser system (10) for producing a linear laser marking (34) on a projection surface (33) comprises a laser beam source (11), which produces a laser beam (25) and emits the latter along a propagation direction (26), a first beam shaping optical unit (12), which is embodied as a collimation optical unit and which has a first optical axis (13), and a conical mirror (14), which is embodied as a right cone with a cone axis (15) and a reflective lateral surface (22) and which is disposed downstream of the collimation optical unit (12) in the beam path of the laser beam, with the cone axis (15) being aligned parallel to the first optical axis (13). The laser system (10) comprises a second beam shaping optical unit (16), which is disposed upstream of the conical mirror (14) in the beam path of the laser beam and which shapes the laser beam into an annular beam (28) with an intensity minimum in the beam center.
