Device for shaping laser radiation, comprising - homogenizing means which can homogenize a plurality of component beams or a plurality of groups of component beams of the laser radiation separately in such a way that, the component beams or groups of component beams emanating from the homogenizing means can respectively generate in an operating plane a linear intensity distribution (9, 19) with finitely steeply sloping edges at the line ends, and - superimposing means which comprise a lens array with a plurality of lenses arranged next to one another in an arrangement direction, the superimposing means serving to superimpose the component beams or groups of component beams in such a way that it is possible to generate in the operating plane a linear intensity distribution (11, 20) whose length in the arrangement direction of the lenses is greater than the length of each of the linear intensity distributions (9, 19) of the component beams or groups of component beams in the arrangement direction of the lenses, - the following condition being valid for the lenses of the lens array: 2 ⋅ F ⋅ NA 50 % = M ⋅ P 2 - where M = 1, 2, 3,..., - F being the focal length of each of the lenses, - P 2 being the centre-to-centre spacing of the lenses, - and NA(50%) being the numerical aperture of each of the lenses, defined via that angle for which the intensity of light passing through the lenses has dropped to half, - the homogenizing means and/or the lens array being arranged and/or designed in such a way that one of the component beams or a group of component beams passes through each of the lenses, characterized in that the lens array of the superimposing means is a unipartite lens array. - homogenizing means which can homogenize a plurality of component beams or a plurality of groups of component beams of the laser radiation separately in such a way that, the component beams or groups of component beams emanating from the homogenizing means can respectively generate in an operating plane a linear intensity distribution (9, 19) with finitely steeply sloping edges at the line ends, and - superimposing means which comprise a lens array with a plurality of lenses arranged next to one another in an arrangement direction, the superimposing means serving to superimpose the component beams or groups of component beams in such a way that it is possible to generate in the operating plane a linear intensity distribution (11, 20) whose length in the arrangement direction of the lenses is greater than the length of each of the linear intensity distributions (9, 19) of the component beams or groups of component beams in the arrangement direction of the lenses, - the following condition being valid for the lenses of the lens array: 2 ⋅ F ⋅ NA 50 % = M ⋅ P 2 - where M = 1, 2, 3,..., - F being the focal length of each of the lenses, - P 2 being the centre-to-centre spacing of the lenses, - and NA(50%) being the numerical aperture of each of the lenses, defined via that angle for which the intensity of light passing through the lenses has dropped to half, - where M = 1, 2, 3,..., - F being the focal length of each of the lenses, - P 2 being the centre-to-centre spacing of the lenses, - and NA(50%) being the numerical aperture of each of the lenses, defined via that angle for which the intensity of light passing through the lenses has dropped to half, - the homogenizing means and/or the lens array being arranged and/or designed in such a way that one of the component beams or a group of component beams passes through each of the lenses,
