An optical element includes an optical material including a first edge and an opposing second edge. The optical element further includes a plurality of micro-channels arranged within the optical material. Each of the micro-channels of the plurality of micro-channels extends from the first edge to the second edge of the optical material.

Robust method for bonding optical materials

A processing technique for production of fused silica for radomes and like elements is described. The processing technique includes forming a mixture of milled silica having an average particle size of about 1 to 5 microns, and a colloidal silica. This mixture is processed to form fused silica having substantially high strength.

Fused silica and method of manufacture

Systems and method for forming a nanocomposite material. One example of a nanocomposite material includes a first sulfur-based nanoparticle material defining a first nanophase and a second sulfur-based nanoparticle material defining a second nanophase, wherein the nanocomposite material is at least partially long-wave infrared (LWIR) transmitting, and the first nanophase and the second nanophase are co-dispersed to form interpenetrating networks with one another and each has a grain structure that is distinct from one another.

Long wave infrared transparent window and coating materials

A method for forming a cooling structure having a plurality of cooling members. The method includes: providing a template having a plurality of features, such members projecting outward from a base of a template or holes passing into the template, the features being arranged in a predetermined pattern, such pattern being selected in accordance with the predetermined pattern of cooling members; and forming a conformal coating of diamond over the features.

Cooling structure for integrated circuits and methods for forming such structure

A method of making aluminum oxynitride includes introducing a mixture having aluminum oxide and carbon into a chamber, agitating the mixture within the chamber, and heating the mixture to make aluminum oxynitride.

Method of making aluminum oxynitride

A method for increasing the optical transmission characteristics of zinc sulfide in the visible and infrared portions of electromagnetic spectrum is described. Materials such as metals and, in particular, transition metals are diffused through the zinc sulfide material over a duration of time sufficient to cause the material to turn substantially water clear and substantially colorless.

Zinc sulfide bodies having improved optical transmittance

A technique for increasing the strength of long wavelength infrared material, such as zinc sulfide and zinc selenide includes diffusing species which are applied to the materials as thin films into the zinc sulfide and zinc selenide material. Portions of the thin film material are thermally diffused to substantial depths of up to 100 microns below the depth of flaws formed in the body using one of two diffusion techniques. One diffusion technique uses hot isostatic pressure and the other uses a heat treatment carried out at or near ambient pressure in an inert atmosphere, such as argon or other suitable inert gas.
