Future IRCM laser transmitters are being developed based on optically pumped GaSb mid-infrared semiconductor laser, however, the current technology requires the laser to be operated at cryogenic temperature. Aculight and MIT Lincoln Laboratory propose toinvestigate methods to increase the operating temperature of these semiconductor lasers, which will dramatically decrease the cost of the laser t ...

We propose a Yb:SFAP laser system, using a novel resonator scheme, that will provide over 1 J per pulse output at 100 Hz at high efficiency, in a package far more compact, lower mass and efficient that conventional systems. The high-pulse-energy poweroscillator architecture is especially suited to space platforms where weight, volume, cooling and efficiency are particularly important. The propos ...

Advanced IRCM lasers and systems, currently in development, require mid-infrared semiconductor lasers with very non-standard design parameters. The proposed effort will investigate the performance of commercially grown GaSb based materials and optimizetheir performance for use in unique laser transmitter designs, which will be directly traceable to future IRCM systems. The proposed mid-infrare ...

The objective of this proposal is to demonstrate methods for extending the Battlespace Infosphere to mobile platforms using optimized COTS technologies. The 1999 USAF Scientific Advisory Board report titled Building the Joint Battlespace Infosphereidentifies the eXtensible Markup Language (XML) as one of the most promising technologies for representing JBI information objects. Indeed, many DoD use ...

The Force Template will provide JBI management processes with the semantic content they require. But determination of what those processes are, and hence what information and interactions the FT mechanism must support, requires experimentation with aworking infosphere and these semantic models will inevitably change over time. What is required is a flexible approach to building Force Templates tha ...

Evaporative spray cooling systems are perhaps the only systems capable of the high power density thermal control anticipated for future spacecraft. However, evaporative spray cooling in the micro-gravity environment poses particular challenges foreffective system design because of the complications imposed by the

Phase 1 develops an innovative approach for GPS antijam CRPA antennas using miniature multi-arm spiral elements to form a CRPA. The technique leverages experience with antijam technology, supercooling, and spiral antenna CRPA development. This combinationof technologies and capabilities will result in a small, robust and innovative CRPA antijam solution for munitions. The effort will focus on the ...

This SBIR Phase 1 effort will develop micro-discharges to power a micro-thruster rocket. The micro-discharges and arrays of these devices are made using semiconductor processing methods. Ultimately they will be very inexpensive to manufacture in largenumbers. We will explore enhancing the power deposition rate in low molecular weight gases appropriate for high thrust. We will examine the curre ...

A Rolls Royce AE3007 Engine powers the Global Hawk UAV. In order to start the engine, an Air Turbine Starter is required. Since the UAV does not have an Auxiliary Power Unit on board, this engine could only be started on the ground. This means that in caseof a flame out this aircraft could be lost. Therefore, the ability to start the engine in the air would contribute significantly to the UAV surv ...

InPhot Inc proposes to develop the enabling material and device technology for the realization of low noise, large area, high quantum efficiency infrared Avalanche Photodiode Detectors (APD) sensitive in the 1064 nm to 1550 nm spectral region for lasercommunication. We will achieve this by performing device designs to determine suitable material structures, epitaxial growth and device fabrication ...
