    摘要: An optical element comprises a transparent substrate. An antireflection coating is provided on the substrate for reducing reflections of wavelengths from approximately 700 nm to approximately 1700 nm. The coating comprises a plurality of stacked, uniform layers with refractive indices which decrease toward the top of the stack. A base coating is arranged between the layer stack and the substrate. The effective refractive index at the top of the base coating is at least 2.5, and the base coating is a graded index layer.

    摘要: A multilayer optical component is provided in thin-film technology. The component comprises a monocrystalline substrate 1, for example a garnet substrate, which supports a stack 2 of monocrystalline layers 11-16, for example garnet layers, provided epitaxially on the substrate. The layers have alternately a high and a low refractive index and as regards thickness and refractive index are optimized to minimally or maximally reflect electromagnetic radiation of a given wavelength in the infrared or optical range of the spectrum. Said optical component is suitable in particular for use in high-power lasers.

    摘要: A method of providing a transparent layer of aluminum oxide or a layer stack of aluminum oxide and one or more other metal oxides on a substrate by providing the Al and optionally the other metals on the substrate and then oxidizing the assembly electrolytically is shown in which a conductive layer of tin oxide and indium oxide and/or cadmium oxide, if necessary doped to increase the conductivity, is provided between the Al and the substrate. As a result of this the Al is converted completely into oxide so that an optical transmission is obtained which is as high as possible.
