We propose to develop a fiber-based, high power, narrow linewidth, and tunable THz source to implement a novel THz spectroscopy system by leveraging our proprietary fiber laser technology. This proposed high power fiber-based THz source will be generated by using a nonlinear crystal based on difference-frequency generation (DFG) pumped by high power pulsed fiber lasers in MOPA with high repetition ...

In this proposal, we propose to demonstrate and build a widely tunable, low phase noise, narrow linewidth, single frequency fiber laser by developing an innovative Er/Yb-co-doped polarization maintaining (PM) single mode fiber. Such a fiber laser is needed for advanced fiber optical towed array sonar systems. In Phase I, we will design and fabricate this new fiber, demonstrate fixed wavelength low ...

The Department of Energy has identified a need for a single-polarization, mode-locked, high-power, 2-micron fiber laser for an advanced laser electron accelerator. The 2-micron laser wavelength would allow for both larger accelerator dimensions and the acceleration of more charge, compared to the 0.8 micron Ti:Sapphire laser. Another advantage of the 2-micron wavelength is the possibility of using ...

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 ...

The Small Business Innovation Research (SBIR) Phase I project will investigate the feasibility of developing autonomic-healing hot mix asphalt. A major objective of this proposed study is to develop self-healing hot mix asphalt (by means of phase-dispersion of healing agent) that would actively arrest microcracks. This study will involve mechanical tests to determine the healing efficiency of auto ...

AED Corp., C-K Technologies, Control Systems inc, and Digital-Engines will structure and focus their collective expertise to design, optimize technologies, build, test, and develop a 650-hp advanced diesel technologies demonstrator. The work will be supported by AED’s Phase II Advanced Military Diesel Engine (AMDE) program. During Phase I this team of experts incorporated AMDE design feature ...

Today’s Warfighter often carries an inordinate load that can lead to injuries and encumbered performance. Equipment is distributed among squad members with little, if any regard for differences in strength and anthropometry. Consequently, the current focus on human-centric design requires a modeling and simulation tool that can reduce the load Warfighters carry and can help distribute equipmen ...

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 ...

DESCRIPTION (provided by applicant): A growing number of potential native and engineered biothreat agents effectively limit the proactive protection of public health through vaccination. An alternative approach relies on the use of corresponding protective antibodies that are pre-made and are used as injectable drugs in reactive rather than proactive mode. The implementation of this approach, how ...

The proposed Phase II STTR program will implement forward-error correction and other processing, as well as coherent transceiver operation, in order to improve the performance of underwater communications systems. Significant reduction in the bit-error rate will be demonstrated under both shot-noise and ambient-noise limited conditions.
