Laser system for generating a linear laser marking

A laser system () for generating a linear laser marking () on a projection surface (), including a laser beam source (), which generates a laser beam () and emits it along a propagation direction (), a first beam shaping optical unit () embodied as a collimation optical unit and having a first optical axis (), and a conical mirror () which is embodied as a right cone having a cone axis () and a reflective lateral surface () and is arranged in the beam path of the laser beam downstream of the collimation optical unit (), wherein the cone axis () is oriented parallel to the first optical axis (). The laser system () includes a second beam shaping optical unit (), which is arranged in the beam path of the laser beam upstream of the conical mirror () and reshapes the laser beam into a ring beam () having an intensity minimum in the center of the beam.
