Abstract: An electrochemical additive manufacturing method includes positioning a build plate into an electrolyte solution. The conductive layer comprises at least one conductive-layer segment forming a pattern corresponding with a component. The method further comprises connecting the at least one conductive-layer segment and one or more deposition anodes to a power source. The one or more deposition anodes correspond with at least a portion of the pattern formed by the at least one conductive-layer segment. The method additionally comprises transmitting electrical energy from the power source through the one or more deposition anodes of the plurality of deposition anodes corresponding with the at least the portion of the pattern formed by the at least one conductive-layer segment, through the electrolyte solution, and to the at least one conductive-layer segment, such that material is deposited onto the at least one conductive-layer segment and forms at least a portion of the component.

Abstract: A moisture sensitive optically nonlinear crystal is enclosed in a hermetically sealed elongated vacuum cell. The vacuum cell has an input window at one end and an output window at an opposite end providing optical access to the crystal by a laser beam. The windows are attached to the cell by cold-formed, indium-metal ram-seals. In an example of the cell in which the crystal is arranged to generate UV radiation from the laser beam, the output window is located at a sufficient distance from the crystal that the flux of UV radiation incident on the output window is below the damage threshold of the window for the UV radiation.

Abstract: The invention is a photovoltaic window panel comprising a parallel array of strips of photovoltaic cells incorporated within the body of a transparent panel such that the active area or surface plane of a photovoltaic cell is nearly perpendicular to the plane of the transparent panel. The narrow strips of photovoltaic cells are inserted into slots formed in the transparent panel with the strips encapsulated within the slots with a clear potting material. The slotted panel containing the strips of photovoltaic cells is protected by lamination with a clear protective cover. Alternatively the strips of photovoltaic cells may be molded into a panel of transparent material. The electrical outputs of each strip of photovoltaic cells emerge from the two side edges of the transparent panel so that the strips of photovoltaic cells may be connected in parallel or in series to contacts external to the photovoltaic window panel.

Abstract: An optical fiber assembly includes a clad optical fiber having an end-cap thereon. Radiation is focused into the optical fiber via the end-cap. A roughened portion of the fiber cladding behind the end-cap allows any radiation focused into the fiber and propagating in the cladding to escape the optical fiber. A concave reflector surrounding the optical fiber reflects the escaped radiation away from the fiber assembly. A connector for connecting the optical fiber to a laser includes an air-cooled beam-dump for receiving the radiation reflected away from the optical fiber.

Abstract: A truncated triangular prism has an entrance and an exit face perpendicular to each other and a reflecting face inclined at an angle ? to the entrance face where ? is about 135°??B, and where ?B is the external Brewster angle for the material of the prism at the wavelength of radiation to be reflected by the prism. A beam of p-polarized radiation directed into the prism through the entrance face at the Brewster angle is totally internally reflected from the reflecting face and leaves the exit face at the Brewster angle and at an angle of ninety degrees to the direction at which the radiation enters the prism.

Abstract: Negative Group-delay-dispersion mirror (NGDD-mirror) multilayer structures include a generally-orderly arrangement of layers or groups of layers in which the function of certain individual layers or groups of layers can be recognized and defined. The structures are broadly definable as a rear group of layers which are primarily responsible for providing a desired reflection level and reflection bandwidth together with a low and smoothly varying reflection phase-dispersion, and a front group of layers which are primarily responsible for producing high reflection phase-dispersion necessary for providing a desired NGDD level and bandwidth. The front group of layers relies on multiple resonant trapping mechanisms such as two or more effective resonant-cavities, employing one or more sub-quarter-wave layers to shape the phase-dispersion for providing a substantially-constant NGDD.

Abstract: A multi-layer high reflective dielectric optical coating deposited on a laser diode facet that shifts the high amplitude peak of the electric field associated with the reflection of light away from the interface between the semiconductor material and the reflective coating, and into the reflective coating itself. By shifting the electric field peak in this manner, the laser diode can operate at much higher optical output powers without inducing catastrophic optical damage at the non-output facet.
