A low-cost fiber-based octave-spanning frequency comb system operating in the mid-IR region is proposed, which is based on femtosecond-Tm-fiber-laser-pumped supercontinuum generation in a mid-IR-transmitting dispersion-engineered fiber. An all-fiber femtosecond mode-locked Tm-doped fiber laser at 2 micron will be used as a seed source for mid-IR supercontinuum generation. A femtosecond soliton fib ...

The DOE needs a single-polarization mode-locked high-power 2-micron fiber laser for an advanced laser electron accelerator. The 2-micron laser wavelength allows for larger accelerator dimensions and the acceleration of more charge, compared to the 0.8 micron Ti:Sapphire laser. The other advantage of a 2-micron wavelength is the possibility of using silicon as opposed to quartz as a material for ...

The DOE needs long-wave infrared transmitting optical fiber to support remote sensing systems for the detection of nuclear proliferation activities. This project will develop a new class of advanced infrared, transparent, single mode fibers having propagation loss less than 3 dB/m in the 8-12 micron range, rugged mechanical properties, and high optical power delivery capacity. The transition tem ...

An approach to make a long endurance UAV with an 18 hour endurance and large payload will be developed based on an existing, fielded capability present operationally deployed.  The system will be built from COTS equipment minimizing cost and allowing for rapid maintenance and upgrading of the system as technology develops.  The system will be fully autonomous through launch, mission flight and r ...

This proposal will provide immediate decision support data, enabling appropriate and cost effective responses (shut down vs. continue) for training exercises/facilities. Specifically, the DoD requires the ability to “train as we fight and fight as we train”, however training is severely limited by visible emissions compliance in the current regulatory environment. Regulated facilities will hav ...

The AEgis Technologies Group Inc. proposes to investigate high energy laser and high power microwave instrumentation for ground and airborne targets. The experienced team will identify candidate instrumentation systems; evaluate them against customer-defined requirements and features; and recommend potential systems for further study, development, and implementation in Phase II. We will coordinate ...

Laser eye protection has become increasingly important due to the availability of laser sources (continuous and pulsed) over a broad range of wavelengths. This is particularly the case where table top femtosecond laser pulses (~50femtoseconds) with peak powers reaching the Terawatt  scale are commercially available in the visible and near infrared.  The military uses many laser systems (e.g., tr ...

Today¿s solid-state lighting (SSL) products fall short of the key price and performance requirements needed to meet the complex demands of the general illumination market. Therefore, this project will develop novel encapsulants for LEDs that have the potential to improve light extraction efficiency by 30% over current technology. The approach will involve the synthesis of ionic liquids and soli ...

ASI proposes an innovative and numerically-efficient approach to the modeling of crack propagation in solid propellant rocket motors.  Our technology uses a coupled fluid-structure interaction model that is enhanced with an embedded grid capability.  Such an approach eliminates virtually all of the bottlenecks that occur in traditional approaches, through elimination of the re-gridding that must ...

This proposal describes a specific problem within the Intelligence community. Because of a lack of GEOINT tools for capturing storing and delivering expert knowledge from experienced analysts, new analysts have difficulty in quickly gaining the level of skill that those expert analysts possess.  Recent work in cognitive science has shown that engineers presented with knowledge from domain experts ...
