Method for printing a micro-scaled or nano-scaled XUV and/ or X-ray diffractive optic, including the following steps: a) providing a material with a first component being photo-sensitive and being polymerizable by two-photon-absorption, b) providing data of a desired geometrical structure of the optic and creating at least one trajectory corresponding to the data of the desired structure of the optic, c) providing a first high-intensity energy beam, in particular a laser beam, wherein the beam comprises a focus having a position being adjustable to a plurality of positions (F1, F2,..., F8) being coincident with the at least one trajectory, d) wherein at least one further high-intensity energy beam is provided, wherein the first and the at least one further high-intensity energy beam intersect each other in an intersecting volume within the material, wherein only in the intersecting volume, a sum of energies provided by the focus of the first beam and a focus of the at least one further high-intensity energy beam exceeds a threshold value necessary for initiation of polymerization by two-photon-absorption, e) polymerization of the material by two-photon-absorption at a first position of the focus, thereby creating a first voxel of the structure of the optic, f) adjusting the position of the focus from the first position to a subsequent position of the focus along the at least one trajectory and repeating step d) at the subsequent position of the focus, wherein a distance (d) between each of the positions (F1, F2,...,Fp) of the focus and at least one of the rest of the positions (F1, F2,...,Fp) of the focus is smaller than a mean diameter (vd) of the voxels (V1, V2; V1, V6; V2, V3; V2, V5; V3, V4; V4, V5; V4, V8; V5, V6; V6, V7) produced at these positions with respect to their dimension parallel to the distance (d). a) providing a material with a first component being photo-sensitive and being polymerizable by two-photon-absorption, b) providing data of a desired geometrical structure of the optic and creating at least one trajectory corresponding to the data of the desired structure of the optic, c) providing a first high-intensity energy beam, in particular a laser beam, wherein the beam comprises a focus having a position being adjustable to a plurality of positions (F1, F2,..., F8) being coincident with the at least one trajectory, d) wherein at least one further high-intensity energy beam is provided, wherein the first and the at least one further high-intensity energy beam intersect each other in an intersecting volume within the material, wherein only in the intersecting volume, a sum of energies provided by the focus of the first beam and a focus of the at least one further high-intensity energy beam exceeds a threshold value necessary for initiation of polymerization by two-photon-absorption, e) polymerization of the material by two-photon-absorption at a first position of the focus, thereby creating a first voxel of the structure of the optic, f) adjusting the position of the focus from the first position to a subsequent position of the focus along the at least one trajectory and repeating step d) at the subsequent position of the focus, wherein a distance (d) between each of the positions (F1, F2,...,Fp) of the focus and at least one of the rest of the positions (F1, F2,...,Fp) of the focus is smaller than a mean diameter (vd) of the voxels (V1, V2; V1, V6; V2, V3; V2, V5; V3, V4; V4, V5; V4, V8; V5, V6; V6, V7) produced at these positions with respect to their dimension parallel to the distance (d).
