Abstract: A device for beam forming includes at least two laser light sources capable of emitting laser radiation and an optical device capable of influencing the laser radiation such that the laser radiation has an intensity distribution in a working plane that at least partially corresponds to a top-hat distribution at least with regard to one direction.

Abstract: A device for homogenizing laser radiation has at least in a first direction perpendicular to a direction of propagation of the laser radiation partial beams spaced apart from each other, in particular for homogenizing laser radiation emanating from a laser diode bar, an array of refractive surfaces, which can deflect at least a majority of the partial beams of the laser radiation to be homogenized in such different manners that the beams run at least partially more convergingly to each other after passing through the refractive surfaces than before passing through the refractive surfaces. The device further has a lens device through which the partial beams, which have passed the array of refractive surfaces, can pass, wherein the lens device can superimpose at least some of the partial beams in a working plane.

Abstract: Device for shaping laser radiation which has sub-beams (3) spaced apart in a first direction (X) perpendicular to the propagation direction (Z) of the laser radiation, in particular for shaping laser radiation which is output by a laser diode bar (1), comprising a first refractive interface (8) which can differently deviate at least a multiplicity of the sub-beams (3) of the laser radiation to be shaped, so that they travel at least partially converging together after passing through the first interface (8) more than before passing through the first interface (8), and furthermore comprising a second refractive interface (9) through which the laser radiation can pass after having passed through the first interface (8), the second interface (9) being able to deviate at least some of the sub-beams (3) so that their convergence is reduced.
