Abstract
An optical arrangement converts an input laser beam into a line-like output beam, which propagates along a propagation direction and which has, in a working plane, a line-like beam cross section extending along a line direction. The optical system includes: a reshaping optical unit having an input aperture, through which the input laser beam is radiated, and an elongate output aperture, elongatedly extending along an aperture longitudinal direction, the reshaping optical unit converting the input laser beam radiated through the input aperture into a beam packet exiting through the output aperture; and a homogenization optical unit which converts the beam packet into the line-like output beam, different beam segments of the beam packet being intermixed and superimposed along the line direction. The aperture longitudinal direction extends in a manner rotated about the propagation direction by a non-vanishing angle of rotation with respect to the line direction.
