Abstract: This disclosure describes a method for producing a functional element that includes a substrate made substantially of a polymer. On at least one surface of the substrate, there is at least one zone with a distinct surface texture. The method involves irradiating a specific surface region of the substrate with laser radiation during a laser-processing step. This irradiation induces a change in the volume of the polymer near the surface, caused by the interaction between the laser radiation and the polymer. The result is a permanent change of the surface texture within the targeted zone. The substrate is composed of a hydrous polymer, and the process is optimized by selecting a working wavelength of the laser-processing operation such that the polymer's degree of absorption is appropriate. This selection is based on a functional relationship among the laser wavelength, the polymer's water content, and its absorption characteristics, ensuring precise surface modification.

Abstract: A method of preparing a sample for microstructure diagnostics on a sample body by material-ablating processing, and subsequently producing an examination region on the sample portion, the examination region including a target region to be examined, the method including producing a terracing zone including the target region on at least one surface of the sample portion, wherein at least one notch with flanks extending obliquely in relation to the surface is produced next to the target region by material-ablating beam processing to produce the terracing zone, and ablating material from the surface of the sample portion in the region of the terracing zone by an ion beam, which is radiated under grazing incidence onto the surface obliquely to the direction of extent of the notch such that the target region lies behind the notch in the incoming radiation direction of the ion beam and, as a result of the terracing in the region behind the notch, the surface is recessed substantially parallel to the original height

Abstract: A sample for microstructure diagnostics includes a sample body holder with accommodation structures to accommodate a sample body in a defined accommodation position; and at least one sample body produced separately from the sample body holder, the sample body having at least one solid handling portion and, adjoining the handling portion, a target portion thinner relative to the handling portion, the target portion being delimited at a narrow side by a sample body top side and, laterally, by side faces extending in a perpendicular or oblique manner in relation to the sample body top side, with the sample body being affixed to the accommodation structures in the accommodation position.

Abstract: A method of producing a micromachined workpiece by laser micromachining includes applying a protective layer (SS) to a surface (OF) of the workpiece (WS) and machining the surface in a machining area by a laser beam (LS) through the protective layer, wherein the protective layer (SS) is produced using a coating fluid (SF) containing an at least partially volatile carrier liquid (TF) in which metallic and/or ceramic particles (PT) are dispersed; the coating fluid (SF) is applied to the surface (OF) such that at least the machining area (MA) is covered with a protective coating fluid layer (SSF); the applied coating is dried to reduce the content of carrier liquid (TF) such that a protective layer (SS) forms, which is essentially composed of the particles (PT) of the applied coating fluid or of these particles and a reduced content of the carrier liquid relative to the coating fluid; and machining of the machining areas is carried out by a laser beam (LS) irradiated through the protective layer onto the workpie
