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 ...

Recent advances in THz-source stability, power and practicality have opened the door for active THz imaging in both commercial and military settings. AEgis is teaming with U Buffalo to develop a THz detection device that utilizes classical rectification effects in semiconductor point contacts (SPCs) to achieve response in the 1 to 10 THz range and is capable of operating at temperatures over 150 K ...

The Laser Irradiance Measurement on Target (LIMT) project will provide a sensor mesh for direct, on-target measurement of laser beam characteristics of interest (e.g., irradiance level, beam size, time history of beam shape). Activities during Phase 1 of this project include identification and prioritization of requirements; design of system and subsystem components; evaluation of component design ...

In our proposed effort, we intend to perform high temperature (100-200 Deg C) characterization of an ultra-advanced heat pipe to determine feasibility of using it in high temperature space radiators. In previous work, we have shown that the so-called "Qu Tube" achieves exceptionally high thermal transport rates at lower temperatures. BENEFIT: Our innovation will significantly reduce the size of ...

The mission of this proposed research is to develop ultracapacitors (also known as electrochemical or supercapacitors) to address an array of military applications. These applications include pulsed power for directed-energy and kinetic-energy weapons, sensors, and power supplies and control systems for aircraft and spacecraft. The proposed innovation employs carbon nanotubes (CNTs) coated with p ...

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 ...

AEDC personnel have developed and demonstrated the effectiveness of coupling a control volume model with a wind tunnel control system. The performance of the model was hampered because parameters of the model were assumed to be constant, when they are likely variables. A method for using facility data to determine functional relationships defining these parameters would allow them to vary during ...
