High power fiber lasers have made significant progress in last several years. Fiber laser operating in the 1.9-2.1micron wavelength regimes have achieved operating powers approaching 1kW. Such fiber lasers have great potential in the areas of laser radar, remote sensing, medicine, and infrared (IR) countermeasures. However, further development of these technologies is hindered by a lack of commerc ...

An all-fiber mid-infrared laser source offers many unique features that are key to next-generation infrared countermeasure systems. We propose a low-cost all-fiber mid-infrared light source operating in 2-5 micron wavelength range with ~1000watt average output power, based on our proprietary infrared glass/fiber technology. All-fiber monolithic design allows us to develop such a low-cost fiber las ...

High spatial resolution infrared imaging fiber bundles are needed to spatially analyze combustion processes accessible only by probe penetrations into high pressure and/or high temperature regions such as turbine combustors and afterburners. Specialized infrared fibers including chalcogenide and ZBLAN fibers are typically very expensive and brittle and fragile. We propose to develop an innovative ...

High power fiber lasers have made significant progress in last several years. Several kW of output power has been demonstrated, which enables a wide range of new applications from laser welding, laser cutting, and laser drilling to military defense. While high power fiber lasers have been successfully deployed in industry, one piece of critical components, fiber isolator, is still not available. F ...

For Phase I, an ultra low power, high performance microprocessor core using a combination of double-gated and independent double-gated Flexfet™ SOI CMOS technology from American Semiconductor will be designed to address the requirements of military and space communication systems. High integration feasibility using Flexfet technologies followed by confirmation of the power and performance improv ...

Improvements in silicon-on-insulator (SOI) technology have resulted in development of monolithic chip designs for radiation image sensors and particle detectors by facilitating the use of the handle silicon layer for the detectors and the SOI layer for the readout circuits. Unfortunately, even the most advanced SOI-based imagers are still limited in effectiveness due to threshold (Vt) shifts when ...

The ion exchange membrane is the key component in redox flow batteries (RFBs) as it critically determines the RFB performance and its economic viability. The membrane should possess the following properties to ensure high energy efficiency and long cycle life of RFBs: high proton conductivity, low permeability of active redox species, and high chemical stability. In addition, low cost and high d ...

Current state-of-the-art, high voltage, pulsed power systems designed to drive high power microwave (HPM) sources utilize Marx generator designs. The high voltage insulation of these devices has been traditionally based on either high dielectric strength oil or sulfur hexafluoride (SF6). The dielectric strength of the insulating medium determines the minimum size of the tank enclosure of the Mar ...

We propose to implement a novel countermeasure against the exploitation of integrated circuit hardware. The proposed countermeasure is applicable to both FPGAs and ASICs, increases design obfuscation and promises to block embedded hardware exploits. It also is fully compatible with virtually any other hardware exploit countermeasure and reduces forensic costs when exploits are suspected. The propo ...

This program is expected to result in a high-temperature heat pipe passive cooling system for space-borne phased array antennas. The innovative approach chosen for this project will result in a reliable g-force independent cooling system that is robust against launch and vibration forces as well as the zero-g environment of space. The system is lightweight, inexpensive, and efficient, and has th ...
