Thulium doped fiber laser near 2 micron is of great interest because of the potential possibility of combining high efficiency, high output power, and retina safety together. This proposal is for the development of new Tm-doped glass fiber for efficient high power 2ƒnmicron fiber laser capable of generating an output power of up to thousands watts. The doping concentration of the proposed glass f ...

In the phase I program, Advanced Ceramics Research, Inc. (ACR) fabricated in situ metallic foams by using a unique water-soluble polymer blend and ACR's Extrusion Freeform Fabrication (EFF) method. When the green parts were heated for binder burnout, thebinder was found to foam and create uniform closed, high-aspect ratio porosity. The freeform fabrication also could create open porosity ranging f ...

As the current trends in transistor miniaturization are continued down to the molecular level ( in a dimension of tens of nanometers or less), the electronic properties of solids and solid-solid interfaces are inherently different on the nanometer level.It is becoming clear that continued increases in circuit density will require fairly dramatic changes in the way transistors are designed and ope ...

The terminal objective of this Phase II work will be the development of compact, fully integrated, high-temperature (250 °C), high-power-density SiC-based motor drives for avionics applications. The developed multi-chip power module (MCPM) will target an advanced motor drive application such as actuators (i.e., position control). The initial electrical rating targeted will be a 270 VDC input volt ...

Fast and accurate fault protection and isolation has always been an important feature of electric networks; in particular, this includes high reliability and robust networks such as the electric distribution systems of US Navy warships. This feature, however, is now critical for the development of next-generation warships (such as the Zumwalt Class DDG 1000) due to the present (and future) power ...

Laser-induced breakdown spectroscopy (LIBS) and Raman spectroscopy are developing rapidly for chemical and biochemical sensing applications. There is an urgent need for high-sensitivity detectors so as to minimize sample quantity and maximize detection range from the source. In most field-deployable spectrometers, a photo-detector array is used for analyzing the spectral contents. The sensitivitie ...

This SBIR Phase II project proposed to develop a new fabrication technology that would lead to ultra low-cost, high quality radial gradient refractive index (GRIN) rods, which are widely used in fiber optic communications. Drastic cost reduction isexpected because several cost and labor intensive manufacturing processes will be eliminated, the product yield will be increased significantly compare ...

With the advent of satellite telephone services, it is now feasible to provide secure voice communication to any location on Earth. In a Phase I SBIR for AFRL, Black & Ryan Engineering (BRE) developed VAWCS (Voice Authenticated Wireless CommunicationSystem), a computer model of a Communications Waveform, combining Voice Authentication, Speech Compression, Encryption, and Forward Error Correction ...

In 2004, Breault Research Organization (BRO) was awarded and successfully completed the “Ship Board Lighting System” Phase 1 SBIR. The goal of this project was to develop a new solid-state deck floodlight that met the Navy’s irradiance and uniformity requirements. In addition, the new deck floodlight had to be night vision goggle (NVG) compatible and have a lower life cycle cost than a tra ...

CUBE Technology has created an extremely compact and efficient enclosed combustor dubbed a Micro-Furnace. These Micro-Furnaces have demonstrated an unprecedented operating range and operate on fuels from alcohol to diesel to JP-8. This Micro-Furnace combustor will be the core of the flameless personal water heater. This combustor is fast-starting and delivers its heat via radiation and convecti ...
