Presently there are no broadly tenable, narrow linewidth souces that operate throughout the mid-infrared (mid-IR) region of the spectrum, from 1 to 5 microns. Traditional sources have very low spectral brightness (low power per unit spectral bandwidth). This proposal describes a novel approach to produce a source with very high spectral brightness, tunable over the range of 1.1 to 4.3 microns. ...

The Air Force Phillips Laboratory is seeking approaches for demonstrating frequency agile COIL (chemical oxygen iodine lasers) operating near 1.31 microns and at 10 kHz rep rates. Frequency conversion approaches must be capable of handling high average power levels, greater than 10 kWatts. Converting a COIL device to high peak powers will be necessary for frequency conversion. The approach prop ...

High power lasers are needed for many airborne applications. These lasers must be compact, reliable in high vibration environments, and must also have a low per unit cost. Aculight proposes to develop a high repetition rate laser with average power of 10-20 watts using novel packaging designs and manufacturing methods. When fully developed, this technology will provide flight-worthy lasers at a ...

Improving the optical beam brightness of diode laser bars and optically pumped semiconductors is essential for many Air Force and commercial applications. In this proposed work Aculight will build and test a MIT/LL optical approach for decreasing the angular divergence of diode laser bars by a factor of at least 80. The MIT/LL approach will be implemented using Aculight's newly developed optical ...

Although technologies derived under the Integrated High Performance Turbine Engine Technology (IHPTET) initiative should result in higher performance of gas turbine engines, the durability of engine components continues to be one of the most important design issues which impacts their affordability and robustness. It is currently very difficult to measure or predict the fatigue life of engine com ...

Space structures and high-speed interceptor technology can be significantly enhanced if lighter weight composite structural materials that possess inherently high-strength damage-resistant properties can be developed on a cost-effective basis. A novel laminated sandwich composite concept is proposed that has the potential to significantly improve upon stiffened composites in use today. Current sti ...

This Phase I effort is to synthesize and develop material processing systems that possess the mechanical properties, and processing characteristic for use in flexible electronic and photonic devices. We will demonstrate the feasibility of fabricating in this effort to optimize the modulator/switch and investigate ways to render it manufacturable and multichip module packagable. This would include ...

The stress analysis and fatigue life prediction of the bonded repaired damaged zone of the aircraft structure is a challenging problem for designers. The lack of accurate life prediction methodologies limit the utilization of composite materials to repair the damaged structure. It is proposed to develop analytically and experimentally validated computer program modules for stress analysis and fa ...

Integration of many different devices on a single silicon carbide (SiC) substrate is necessary to realize the full potential of high temperature or high power devices for markets ranging from industrial and consumer to military systems to transportation power and control. Integration requires that the entire device package, individual devices, contacts and interconnect materials, be ...
