Through the Phase I SBIR process, Rini Technologies Inc. has demonstrated the feasibility of using evaporative spray cooling to reduce the temperature of high power laser diode stacks below the temperature at which they currently operate. This reductionin temperature, while operating at high power, results in increased laser efficiency, extended lifetime and reliability, as well as the ability to ...

One example where new cooling systems are required immediately is high power solid state phased array microwave transmitters. Used in military and commercial applications, including radar, electronic defense systems, and satellite communication data linksthese electronically scanned antennas are more reliable and efficient than mechanically scanned designs. Prior Mainstream research has already ...

We propose developing a compact, optical fiber-based Raman scattering instrument for rapid, in-situ analysis of composites, solid rocket motors, and propellants. The instrument will incorporate diode laser-based, full-spectrum Raman scattering forcontinuous in-situ remote monitoring of the composite and propellant chemistry. Narrow well defined Raman peaks and lack of sample preparation requirem ...

This Small Business Innovation Research Program will realize substantial improvements in the p-Ge laser gain medium. Far-infrared lasers based on inter-sub-band transitions of holes in p-type Ge span the broad spectral range of 1-4 THz and are the onlysolid state lasers in that region. They hold promise for molecular spectroscopy, chemical sensing, secure free-space local-area communications in ...

THE DEVELOPMENT OF HIGH POWER, LOW IMPEDANCE, LIGHTWEIGHT ENERGY STORAGE TRANSMISSION LINES FOR PULSE-POWER APPLICATIONS IS CRUCIAL FORSMALLER, LIGHTWEIGHT, SPACE-BASED, PULSE-POWER SYSTEMS. DEVELOPMENT OF HIGH DIELECTRIC ENERGY STORAGE LINE TECHNOLOGY WOULD GREATLY REDUCETHE SIZE, WEIGHT, AND COMPLEXITY OF PULSE POWER SYSTEMS UTILIZING THESE TYPES OF COMPONENTS. EFFICIENT TRANSPORT OF 400KV, 100K ...

Refractory metal carbide coatings are important in high temperature applications by offering corrosion protection of the high temperature components. Traditional methods of producing such coatings are expensive and complex. A low temperature polymericbased process to fabricate HfC with low oxygen impurity and high yield is now ready for assessment for coating applications. The attributes of thi ...

Under this Phase I SBIR Kestrel Corporation proposes to demonstrate the advantages of a novel optical technique for measuring wavefront aberrations as a means for aligning large, segmented, space telescopes such as those that might be employed in a SpaceBased Laser (SBL) Weapon system. The same technology has applications as a wavefront sensor for determining aberrations in the transmitted beam. ...
