Abstract: A radiator joint is provided that include a first component, a second component and a weld seam, that together define a bird beak joint. The first component has generally circular cross-sectional profile. At an end of the first body there is a bird beak cut section that forms a first mating surface. The second component can function as a manifold. It has a generally rectangular cross sectional profile and an aperture. The aperture extends along at least two sides of the second component. The weld seam is disposed at the first mating surface and couples the first component to the second component. A fluidic seal is thereby formed between the hollow interior and the exterior while defining a fluid flow path through the first and second components.

Abstract: An optical nanocomposite containing optically active crystals and suitable to be drawn into fiber form, dissolved into solution and subsequently deposited as a thin film, or used as a bulk optical component. This invention integrates compositional tailoring to enable matching of optical properties (index, dispersion, do/dT), specialized dispersion methods to ensure homogeneous physical dispersion of NCs within the glass matrix during preparation, while minimizing agglomeration and mismatch of coefficient of thermal expansion. By tailoring the base glass composition's viscosity versus temperature profile, the resulting bulk nanocomposite can be further formed to create an optical fiber, while maintaining physical dispersion of NCs, avoiding segregation of the NCs.

Abstract: An optical nanocomposite containing optically active crystals (rare earth or transition metal doped) in a suitably index-, dispersion-, thermo-optically matched matrix enables creation of a glass ceramic with unique optical properties. By further tuning the viscosity of the composite, it can be drawn into fiber form, dissolved into solution and subsequently deposited as a thin film, or used as a bulk optical component. Critical to achieving a viable material is closely matching the attributes needed to not only achieve optical function but to enable fabrication under elevated temperatures (i.e., during fiber drawing) or in unique chemical or thermal environments, such as during deposition as a thin film. This invention uses nanosized crystalline powders (nanocrystals—NC), blended with multicomponent chalcogenide glass (ChG) to form an optical nanocomposite.

Abstract: Methods and systems for hybrid gain guiding in laser resonators that combines the features of gain guiding and fiber or other types of lasers into a single system. Hybrid gain guiding in laser resonators is not limited to conventional fiber lasers. Any type of gain guided fiber, index guided or anti-guided, is used as an intracavity element to induce loss on high order modes in an otherwise multimode laser system. The gain guided element contributes little gain to the laser oscillator but allows only the lowest order mode to transmit without loss. When the gain guiding fiber length is selected so the loss for a particular cavity mode is greater than the gain, the cavity mode does not lase. Since the gain guiding fiber induces loss for all laser modes other than the lowest order mode it makes sure that the mode one higher than the lowest order mode does not lase and as a result, no other cavity modes lase.
