Abstract: Transformation device (1) for laser radiation (7), comprising a first array (2) of cylindrical lenses (3) arranged side by side in a first direction (x) and a second array (4) of cylindrical lenses (5) arranged side by side in the first direction (x), it being provided that during operation of the transformation device (1) the laser radiation (7) to be transformed first passes through the first array (2) and then through the second array (4), and wherein in each case one of the cylindrical lenses (3) of the first array (2) is associated with one of the cylindrical lenses (5) of the second array (4) in such a way that an array of reducing telescopes results, wherein the cylinder axes (6) of the cylindrical lenses (3) of the first array (2) enclose an angle (?) greater than 45° and less than 90° with the first direction (x).

Abstract: Device for generating a linear intensity distribution in a working plane (20), comprising at least one laser light source (11), optics (14) which shape the light (12) emitted by the at least one laser light source (11) in a first direction (X) and/or in a second direction (Y), a beam transformation device (13) increasing the beam quality factor (Mx2) with respect to the first direction (X) and decreasing the beam quality factor (My2) with respect to the second direction (Y), as well as an objective (17) acting in the second direction (Y) and a focusing device (18) acting in the second direction (Y), which is arranged behind the objective (17), wherein the objective (17) and the focusing device (18) image into the working plane (20) a plane (19) behind the beam transformation device (13) in which the light (12) in the second direction (Y) has an intensity distribution with a super-Gaussian profile or with a profile similar to a super-Gaussian profile.

Abstract: An apparatus for generating a line-shaped intensity distribution of laser radiation comprises first and second beam transformation devices spaced apart from one another and at least one focusing element to focus laser radiation that has passed through the first and second beam transformation devices into a line-shaped intensity distribution. The apparatus is configured to change the line width of the line-shaped intensity distribution in a line transverse direction by changing a distance between the first and second beam transformation devices.
