Patent number: 7710347Abstract: Methods and apparatus for components according to various aspects of the present invention operate in conjunction with reaction bonded silicon nitride (RBSN). In one embodiment, a missile radome comprises a wall defining the radome body, including a base and a tip. The wall may comprise a core and one or more skins adjacent the core, such as in a sandwich configuration. The core and the skins may have different densities. The radome wall may be configured to transmit wideband RF signals. The RBSN may be extruded to form the radome.Type: GrantFiled: March 13, 2008Date of Patent: May 4, 2010Assignee: Raytheon CompanyInventors: Richard Gentilman, David G. Burks, Derrick J.

Patent number: 7675952Abstract: A glaze encapsulated solid-state laser component. The novel laser component includes a core and a cladding of ceramic glaze disposed on a surface of the core. In an illustrative embodiment, the core is fabricated from a laser gain medium and the cladding material is a multi-oxide eutectic ceramic glaze having a refractivity slighter lower than the refractivity of the gain medium, such that the glaze layer forms a step-index refractivity interface cladding that can effectively suppress parasitic oscillations in the core gain medium. The glaze cladding can be applied by coating the core with the glaze and then firing the glaze coated core, or by fabricating pre-formed cladding strips from the ceramic glaze in a first firing cycle, mounting the pre-formed strips to the core, and then fusing the pre-formed strips to the core in a secondary firing cycle.Type: GrantFiled: December 23, 2004Date of Patent: March 9, 2010Assignee: Raytheon CompanyInventors: Michael Ushinsky, Alexander A. Betin, Richard Gentilman, Patrick K. Hogan

Patent number: 7630423Abstract: A glaze soldered solid-state laser active medium. The novel laser active medium includes a first section of a first material, a second section of a second material, and a layer of ceramic glaze joining the two sections. The first and second materials may be identical, similar, or dissimilar, and may include crystals or ceramics. The glaze is a multi-oxide eutectic ceramic glaze having a refractivity, light absorption, thermal expansion, and fusion temperature that are compatible with the first material. The sections are joined using a novel glaze soldering process that includes the steps of positioning the sections, applying the ceramic glaze between the sections, and firing the glaze to solder the sections together.Type: GrantFiled: April 12, 2005Date of Patent: December 8, 2009Assignee: Raytheon CompanyInventors: Michael Ushinsky, Alexander A.
