摘要： According to various aspects and embodiments, a system and method for providing an optical element is disclosed. In one example, the optical element includes a substrate formed from a Nanocomposite Optical Ceramic (NCOC) material that includes a first oxide nanograin material dispersed in a second oxide nanograin material, and a compressive layer of the NCOC material formed on a surface of the substrate.

摘要： A coupler for separable physically coupling together a pair of objects includes two parts, on opposite sides of a boundary, that have different piezoelectric characteristics. When an electric field is applied to the coupler parts the piezoelectric forces induce a mechanical stress that separates the parts. The parts may be made of the same or a similar material, such as a suitable ceramic material, with the different piezoelectric characteristics produced by templating the parts with different domain orientations, from different seeds, for example using a three-dimensional manufacturing processes. The coupler may be used to allow shock-free (or reduced shock) separation of parts, such as separation of stages of vehicles such as flight vehicles.

摘要： A nanocomposite optical ceramic (NCOC) material. The material having a first solid phase, a second solid phase, and a third solid phase. The first solid phase has first solid phase grains no larger than 5 μm, and each first solid phase grain has a first solid phase grain boundary. The second solid phase has second solid phase grains no larger than 5 μm, and each second solid phase grain has a second solid phase grain boundary. The third solid phase has a doping agent. The doping agent is less than 5 atomic % soluble in the first solid phase and the second solid phase. At least part of the third solid phase is situated at the second solid phase grain boundary.

摘要： A method for forming an optical window. In one example, the method includes depositing a layer of eutectic bonding material onto a first surface of a first section of window material, positioning a second surface of a second section of window material onto the layer of eutectic bonding material such that the first surface is disposed opposite the second surface, and heating the eutectic bonding material to a temperature above a eutectic temperature of the eutectic bonding material and below a melting temperature of the window material for a predetermined length of time to form an optical window. The window material of the first section and the second section may be transparent to infrared radiation and comprise aluminum.
