The device has a positioning system enabling three translational and three rotational degrees of freedom and having a sample holder. The sample holder holds the substrate to which the material to be processed adheres or to which the body to be processed is associated or, in the absence of a substrate, the body to be processed. The device has a laser source emitting laser pulses and focusing optics which shape the laser pulses such that they impinge in a focal point or a focal volume in the region of the material or body to be processed in such a way that a two-photon or multi-photon polymerization takes place.

Abstract: A device for the laser-assisted processing of a material adhering to a substrate or a body that is associated with, or free of, a substrate or of its surface, in particular by TPA/MPA and/or by treatment with an ultrashort pulse laser. A sample holder of a positioning system holds the material to be processed. A laser source emits laser pulses or laser pulse sequences. Focusing optics shape the laser pulses or laser pulse sequences to impinge in a focal point or a focal volume in the region of the material or body to be processed so that a 2- or multi-photon polymerization can take place there, or in that they impinge in a focal point or in a focal volume in the region of the body in such a way that material located there or focal volume is subjected to the desired chemical and/or physical changes.

Abstract: The invention relates to a process for producing a structured shaped body or a layer of this type from a precursor of a metal oxide or mixed oxide selected from compounds of metals selected from among magnesium, strontium, barium, aluminum, gallium, indium, silicon, tin, lead and the transition metals. The process includes at least the following steps: (a) dissolving at least one compound of the at least one metal in an organic solvent and/or exchanging a ligand of the one or more dissolved metallic compounds for a stabilizing ligand, (b) adding a ligand that has at least one photochemically polymerizable group and at least one such group that allows a stable complex formation to the solution and forming a sol with or from the product of this reaction (precursor), (c) applying the sol on a substrate, and (d) exposing the sol anisotropically in such a way that a polymerization of the photochemically polymerizable groups takes place in the exposed areas.
