The need for compact solid state ultraviolet light sources includes clinical light sources for a variety of surgeries, analytical instrumentation sources and communications systems based on shorter wavelengths that will be able to handle higher information densities. Such advanced optoelectric applications demand totally new materials. Of those available, silicon carbide is the most promising for ...

New generation electric lasers offer the potential of a compact, lightweight deployable directed energy weapon with projected power levels into the megawatt range. These systems require power generation sources that can near-instantaneously deliver high levels of clean, stable power to the HEL load without disturbing the weapon platform stability or environment. This Proposed Phase II program adva ...

Department of Defense (DOD) interset in developing laser weaponary in the 1960's. Solid-State lasers have been a canidate technology from the earliest time, but for various reasons, this technology has not been developed to a point where they are scalable to high average power lasers. The development of diode laser pump arrays has improved efficiency, but at a considerable increase in systems cost ...

We propose to adapt angle-only passive ranging methods developed for submarine warfare to the problem of range estimation for missiles using current electro-optical sensor systems in order to provide fire control quality tracking at or near threat burnout to support early intercept. Three methods will be developed: parallax or triangulation ranging; angle rate ranging; and tracker/filter algorith ...

Commercially viable silicon carbide device manufacturing processes depend on an ability to grow'low defect density epitaxial layers. Low defect density epitaxial layers start with pristine SiC substrate surfaces. Epi-ready pristine SiC surfaces are not commercially available. The results of this-programme should remedy this. In Phase I we will demonstrate a cost-effective, reproducible ex-situ sur ...

Applied Mathematics, Inc., proposes to implement and test multi-sensor, multi-platform data fusion software, using state-of-the-art non-linear filters. This effort supports the development of a multi-sensor, multi-geometry picture of threat scenarios, supporting requirement for a single integrated picture of the battlespace. We will test and evaluate the software using threat scenarios of interes ...

An innovative discharge geometry for a very compact, area cooled, high average power CO2 laser employing a two mirror, waveguide-stable optical cavity is proposed. The specific Phase I result sought is the generation of an average CO2 output power of 1 W/cm2 of wall cooling area in a geometry that has a total cooling area of 140 cm2. A lightweight CO2 amplifier version of a future Phase II devic ...

This proposal aims at demonstrating full color large area lamps and pixelated flat panel displays using novel high brightness and fast response cladded nanosphosphores (e.g. ZnCdSe-ZnSe/ZnMgSe cladded quatum dots). These cladded quantum dots, grown in a photoassisted microwave plasma (PMP) metalorganic chemical vapor deposition (MOCVD) reator, are self-assembled in layers to achieve anjection or ...

A novel photoreceiver is proposed based upon the optical sensitivity , gain and impedance transformation properties of an optoelectronic thyristor and HFET integrated circuit. The thyristor is implemented as a vertical cavity device and is compatible withcomplementary HFET digital/analog electronics or complementary bipolar analog/digital gates in a monolithic technology. The thyristor is designe ...
