This disclosure involves a new spinel and glass micro-composite material and process for making such. The composite has excellent transmission in the 0.5-5.0 μm wavelength region suitable for various visible and mid IR applications utilizing windows, domes and other geometric shapes. The composite can be made at a temperature about 40% lower than the glass melting temperature and about 50% lower than the spinel sintering temperature. The composite material has high modulus and fracture toughness which are important for impact resistance in armor and other practical applications.
摘要:
A method for synthesizing Cu(InxGa1-x)S2 and Cu(InxGa1-x)Se2 nanopowders using flame spray pyrolysis to form solar cell absorber materials. The flame spray product is the oxide nanoparticles of the absorber materials (copper indium gallium oxide). The oxide nanoparticles may be deposited directly onto glass substrates. The oxide nanoparticles are then sulfurdized or selenized with a post deposition anneal directly on the substrate to form the absorber layer for a solar cell device.

A spinel ceramic made from the process comprising the steps of polishing one edge of a first spinel part to a surface roughness of less than 1 nm, polishing one edge of a second spinel part to a surface roughness of less than 1 nm, joining the polished edge of the first spinel part to the polished edge of the second spinel part, heating the first and second spinel parts to about 1000-1200° C., and maintaining said heating for about 3-6 hours resulting in bonded spinel parts.
摘要:
A laser apparatus uses a dysprosium doped chalcogenide glass fiber. The glass fiber has a laser pump operatively connected to it. The chalcogenide glass fiber is located in a laser cavity including one or more reflective elements such as a Bragg grating, a Bragg minor, a grating, and a non-doped fiber end face. The apparatus provides laser light output at a wavelength of about 4.3 μm to about 5.0 μm at a useful power level using laser light input at a wavelength of from about 1.7 μm to about 1.8 μm. Also disclosed is a method for providing laser light output at a wavelength of about 4.3 μm to about 5.0 μm using the apparatus of the invention.
