This Small Business Innovation Research Phase I program will determine the practicality of increasing the second harmonic (SH) output of frequency doubling devices by at least 5 times current gutput powers. Altos has demonstrated in preliminary experiments have a 2 times to 3 times increase in SH output by creating thermal gradients across the waveguide structures used to frequency double the lase ...

AstroPower proposes to develop a new ultra-thin gallium arsenide solar cell for space applications, that will result in significantly higher performance compared to conventional gallium arsenide and silicon solar cells. This design incorporates a "floating" junction on the front of the ultra-thin solar cell and a collecting junction at the back of the device. This design will significantly decreas ...

We propose exploratory development of new epitaxial growth technologies for low-defect GiN epitaxial structures and surrogate substrates. A significant feature of our approach is epitaxial latval overgrowth for "defect filtering." We present arguments that such epitaxial lateral overgrowth will lead to GaN material of unprecedented quality with respect to defects, stress, and purity. In the Phase ...

Sensors, capacitors, and conducting features such as resistors and capacitors on circuit boards are produced from metal and ceramic powders 1-12 These powders are manufactured by liquid phase precipitation routes which often start with reduction of metal salts or by solid-state routes where solid reactants are mixed, heated and then milled. The solid-state processing is generally repeated several ...

Optomec Design Company proposes to use Laser Engineered Net Shaping (LENSTM), a Rapid Prototyping and Manufacturing (RP&M) technology currently under development at Sandia National Laboratories (SNL), as a new method for integrating instrumentation (e.g., embedded sensors) into metal structural components. SNL has demonstrated the ability of the LENSTM technology to produce near net shape stainles ...

Glass is an attractive material for microelectronic packaging because it is hermetically sealing, has a low coefficient of thermal expansion, and is compatible with d.c. circuits. Unfortunately, the working temperature of glass is too high for this application. Low-temperature processing of a sol-gel derived, aluminosilicate material for hermetic seals is proposed for electronic packaging. This ...

Breathable release coatings that can withstand processing conditions up to 750F are needed for use on ceramic tooling. In situ removal of volatiles in solvent-based composite processing is a critical issue that will enable production of high quality parts at lower cost per part. Current release coatings meet neither the temperature nor the solvent transport requirements of solvent-based composit ...

Rocket motors that develop greater thrust with lower weight and volume require-ments are an ever present goal of the BMDO. One method of providing this is through formulation of higher energy propellant mixtures. TPL proposes to develop a new method of effectively producing new high perfor-mance propellant constituents for launch, orbit-orbit transfer and station keeping propulsion systems. The p ...

The objective of this research is to demonstrate the feasibility of spray forming aluminum Metal Matrix Composites (MMC) in the solid-state physical form as a light weight structural material. It is anticipated that this innovative manufacturing process will provide opportunities to fabricate near-net-shape spacecraft and interceptor structures with unique material properties. The process called S ...
