Green laser sources are important in advanced naval mine detection as this wavelength has good penetration though seawater. Mine detection programs such as the Coastal Battlefield Reconnaissance and Analysis (COBRA) system and the Airborne Laser Mine Detection System (ALMDS) currently use frequency-doubled 1-µm lasers as the laser source. The generation of green laser light via frequency doubling ...

The focus of our Intelligence and Intuition for Enhanced Decision Making (I2EDM) Phase 1 research is to provide efficient and timely automated production and dissemination of information products in support of doctrinal Decision Points for the Company and below in austere environments. Operating in the Cloud, I2EDM will continuously fuse tactical information with human intuition and experience to ...

This research seeks to develop a method of developing solid-state power amplifiers that operate at 300 Volts, achieve 100 Watt output and greater than 90% efficiency at 1 GHz with 10% bandwidths. We will seek to demonstrate switch-mode amplifiers that use a novel gate design with Gallium Nitride forming the basis for solid state power amplification.

This project is focused on the development of a new generation of GaN-based transistors with breakdown voltages in excess of 1kV that can be used in the demonstration of power amplifiers operating at 1 GHz with power added efficiencies in excess of 90%. To achieve this performance, this project will develop new approaches to increase the breakdown voltage of GaN high electron mobility transistors, ...

The proposed work will address the core physics underlying acoustic reverberation as related to properties of the ocean environment and properties of the acoustic sources, receivers and waveforms that make up ocean-going acoustic systems of interest to the U.S. Navy. Present day active acoustic system performance models, which contain reverberation models as an essential component, are over twenty ...

US troops and equipment are increasingly at risk for irradiation by lasers, whether it be from enemy targeting and ranging systems, designators, or high-energy lasers as weapons themselves. Countering the threat requires detection of the incident laser radiation, the direction from which it is originating, and characterization of its wavelength and temporal profile. Nanohmics Inc., in partnership ...

The proliferation of laser based weapons systems has led to the need for laser threat sensor systems that operate over wide spectral range from the visible to infrared and provide sufficient dynamic range to measure the irradiance levels seen in practice. OPTRA, Inc. proposes a solution based on the complementary combination of CMOS readout integrated circuitry and diffractive optics to provide th ...

The Navy is seeking a new light-weight Atmospheric Diving Suit (ADS) design. This suit must be less than 400 lbs; at this weight a diver will be able to self-propel using his legs and fins. The system must ensure the divers safety at a working depth of 1000 ft of sea-water; protecting the body from the high external pressure at depth, while providing a sustainable 1 ATM internal pressure. Mide in ...

UUV"s have become increasingly important tools in the collection of environmental data. Their unique ability to operate independent of surface vessel conditions allows artic measures when traditional means is not possible. It is now well agreed that artic regions are critical to man"s understanding of the environment. Historically sensor packages for UUV"s have been based on"adaptions"of ship depl ...

We envision a coherently coupled QCL array architecture featuring 2nd order DFB gratings to vertically couple out light with excellent beam quality and high output power. This approach does not require cleaving of the devices or facet coatings and is therefore inherently more robust and manufacturable than facet emitters.
