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.
