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 ...

Feasibility of fabricating IR window materials from aluminum nitride (AlN) will be demonstrated. Aluminum nitride windows are sought as replacements for sapphire windows on high speed seeker missiles because of their higher thermal shock resistance. Our approach is to consolidate high-purity ultrafine powders of AlN to obtain a nanocrystalline window. Small grain size is expected to minimi ...

A long-standing trend in the integrated circuit industry is to reduce pattern geometries on semiconductor substrates. To continue this trend, the next exposure wavelength after on-going deep-ultraviolet (248 nm) will be 193 nm. This SBIR Phase I program will identify and develop thermosetting bottom anti-reflective coatings (BARCs) meeting requirements for use with 193 nm unilayer resists. A serie ...

Ion-implanted, thin polymer films exhibit a large temperature coefficient of resistance which suggests their application in microbolometer arrays used for infrared ( IR) imaging and temperature mapping. Compared to current microbolometer designs which require a series of difficult deposition steps, an ion-implanted polymer-based device requires only a single layer which can be applied by spin coat ...

This proposal describes Phase I of a research and development program to develop and commercialize a compact, affordable Particulate Matter on-line, Real-time, Physical and Chemical Characterization and Monitoring System (PMCMS), that will quickly and accurately analyze the chemical constituents and size distribution of particulate emissions from Air Force Operations. The PMCMS will provide size ...

Duke & Associates will develop a process/material modification for carbon fiber/vinyl ester composite materials which will provide enhanced fiber-matrix adhesion using a low cost, room temperature process such as resin transfer molding (RTM) or vacuum assisted RTM to manufacture high performance composite structures. The program goal is to increase the fiber to matrix strength to that of carbon e ...

A novel 1.57 micron eye-safe micro laser and rangefinder are proposed. The concept results in a laser and detection system with a total weight with batteries of less than 4 ounces each for the micro-transmitter and the miniaturized detection system. Using novel, state of the art laser modeling codes to support our design, we have quantified a range of options for the transmitter and system design ...

A recently patented connectionist paradigm, called the hine hose of thin film growth and removal. Trained by exposure to cumulative experimental data, this paradigm may autonomously compute processing routes toward specifically targeted end goals. In the case of thin film growth and removal, the Creativity Machine ma ...
