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 Helikite Elevated Platform ? Test Relay (HEP-TR) consists of a communications relay payload suspended from a new type of small tethered blimp, called a Helikite, and a Carrier that stores the Helikite and the winch, sensors and helium tanks. TheHEP-TR blimp can be flown at several thousand feet altitude for low cost, long term test communications relay coverage of large areas. It is highly m ...

The goal of this effort is to grow ZnO-GaN hybrid spin LED structures. Two different spin LED structures will be fabricated. Cermet, Inc and Georgia Institute of Technology will grow oxide on nitride and nitride on oxide LED structures through MOCVD. Thequality of the grown structures will be characterized by X-ray, PL, CL and DLTS. Electrical and magnetic properties will be investigated. Based on ...

The goal of this effort is to grow transition metal doped ZnO on native substrates, characterize the films, and design a prototype spin FET based on ZnO. The main objective of phase I will be to demonstrate the growth of high quality homoepitaxial thisfilms of transition metal doped ZnO on ZNO using Cermet's MOCVD technology and in-house fabricated substrates. The quality of the films will be ana ...

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

This SBIR Phase I project builds upon Digital Optics Corporation's experience in the design, fabrication, and integration of micro-optics with lasers, detectors, and fibers to provide an innovative multiplexing approach for fly-by-light (FBL), fiber-basedcontrol of airborne actuator systems. This work will be performed in partnership with Optical Crosslinks and HR Textron.The proposed method uses ...

Many diverse tools are used for the evaluation of propulsion systems from different engineering disciplines. These include legacy codes, off the shelf analysis software such as ANSYS, MathLab a variety of CFD tools, and miscellaneous utilities such asExcel. Engineous Software proposes to investigate integration of diverse propulsion analysis tools into a design system or framework. Such a syste ...
