    摘要： The invention relates to a method for incorporating a structure into a surface of a workpiece that is transparent in a certain wavelength range. For this purpose the surface to be structured is brought into contact with a target surface containing a target material by means of a laser beam, the wavelength of which is within the certain wavelength range, energy is introduced at least at one position through the workpiece and into the boundary region of the surface to be structured and the target surface such that target material is deposited at the respective position in and/or on the surface to be structured. For this purpose a pulsed laser beam having a pulse repetition rate of more than 10 kHz is used, which is focused such that the focus is positioned on or under the target surface, wherein the laser beam has a power density in the focus of more than 2000 W/mm2. The invention further relates to a device for introducing a structure into a surface of a workpiece transparent in a certain wavelength range.

    摘要： The invention relates to a method for incorporating a structure (M) into a surface (O) of a workpiece (W) that is transparent in a certain wavelength range. For this purpose the surface (O) to be structured is brought into contact with a target surface (3) containing a target material by means of a laser beam (2), the wavelength of which is within the certain wavelength range, energy is introduced at least at one position through the workpiece (W) and into the boundary region (G) of the surface (O) of the surface (O) to be structured and the target surface (3) such that target material is deposited at the respective position in and/or on the surface (O) to be structured. For this purpose a pulsed laser beam (L) having a pulse repetition rate of more than 10 kHz is used, which is focused such that the focus is positioned on or under the target surface, wherein the laser beam has a power density in the focus of more than 2000 W/mm2. The invention further relates to a device (1) for introducing a structure (M) into a surface (O) of a workpiece (W) transparent in a certain wavelength range.

    摘要： The invention relates to thermally sprayed Al2O3 layers having a high content of corundum without any property-reducing additives, and to a method for the production of said layers. The invention may be utilized particularly in the field of electrical insulation, as a dielectric, and as protection from wear. According to the invention, the thermally sprayed Al2O3 layers are characterized in that they have a porosity of no more than 19%, and a high content of α-Al2O3 (content of corundum) of at least 72% by volume. The layers have a specific electrical resistance of >1·1012 Ohms·cm, and a purity of >97%. The production according to the invention of said layers is carried out utilizing aqueous or alcoholic suspensions made from pure α-Al2O3, having a grain size of >100 nm by means of a method from the group of thermal spraying.
