Abstract: The present disclosure relates to the production and use of a multi-layer X-ray source target. In certain implementations, layers of X-ray generating material may be interleaved with thermally conductive layers. To prevent delamination of the layers, various mechanical, chemical, and structural approaches are related, including approaches for reducing the internal stress associated with the deposited layers and for increasing binding strength between layers.

Abstract: A novel method for fabricating diamond shells is introduced. The fabrication of such shells is a multi-step process, which involves diamond chemical vapor deposition on predetermined mandrels followed by polishing, microfabrication of holes, and removal of the mandrel by an etch process. The resultant shells of the present invention can be configured with a surface roughness at the nanometer level (e.g., on the order of down to about 10 nm RMS) on a mm length scale, and exhibit excellent hardness/strength, and good transparency in the both the infra-red and visible. Specifically, a novel process is disclosed herein, which allows coating of spherical substrates with optical-quality diamond films or nanocrystalline diamond films.

Abstract: A switchable infrared filter, consisting of a diamond carrier material (1), whereon a filter material (6), which is made of a thermochromic material, is disposed on one side and which can be connected to a heating device (2, 3).

Abstract: The present invention relates to a laser module, comprising a flat substrate basis with a mounting region and with at least one heat conducting region adjoining the mounting region, one heating element arranged in the mounting region and one temperature sensor element arranged in the mounting region.

Abstract: A method for producing a preferably optical polycrystalline diamond element is provided. A substrate having a surface which is complementary to said element is molded and is coated by means of diamond deposition. The diamond element is then removed from the mold. The diamond element is finished either before or after being removed from the mold. The substrate is machine cut in order to form the complementary molded product having at least one spherical surface, whereupon it is covered with a polycrystalline diamond by chemical vapor deposition (CVD).
