Abstract

An optical arrangement converts a laser beam into a line-type beam having a line-type beam cross-section that extends along a line direction with a non-vanishing intensity. The arrangement has: reshaping optics having: an input aperture through which the laser beam is radiated in; and an elongate output aperture, the reshaping optics being configured such that the laser beam radiated in is converted into a beam packet with beam segments that emerge through the output aperture; homogenization optics, which contribute to the conversion of the beam packet into the line-type output beam, and by which different beam segments are mixed and superposed along the line direction; and redirection optics configured to redirect the laser beam such that an incidence position/direction of laser beam on the input aperture is changed in dependence on time.
