Agiltron will develop a new class of chemical vapor analyzer by leveraging Agiltrons development and production of micro-electrical-mechanical systems (MEMS) products and expertise with surface-enhanced Raman scattering (SERS) analysis and film fabrication. Our approach capitalizes on integration of these separate technologies to generate a unique and novel functionality that fully addresses all requirements of this program. The proposed chip-based device contains a micro-sized vapor sampling apparatus coupled with an optical chemical readout. The technical approach will be proven in Phase I through numerical analysis, design, and experiments. Prototype sensors will be produced in Phase II for delivery to the DTRA.

Agiltron Inc. is proposing a mid-infrared, hyperspectral, tomography-based sensor to achieve high sensitivity, accuracy, speed and resolution, and three dimensional chemical/biological warfare agent concentration monitoring in an explosion plume. This innovative approach will leverage Agiltrons existing expertise in gas sensing, spectral imaging, wavelength multiplexing/de-multiplexing, optical component manufacturing expertise. The successful implementation of the proposed research will offer a robust new technology for real time automatic explosion measurement for DOD test labs.

Thin-film, lightweight, large-area flexible inorganic solar cells have shown promise to meet the militarys remote power needs on the battlefield. However, thin film solar cells normally have inferior conversion efficiencies due to limited absorption of sunlight by the thin active layer. Various approaches have been investigated to improve conversion efficiencies of thin film solar cells. Among these approaches, metallic nanostructure induced light scattering or trapping in the thin films have been demonstrated as an effective approach. Another approach to enhance solar cell efficiencies is a broadband, wide angle anti-reflective coating. Therefore, it will be ideal if a coating can perform multi-functions: top electrode, AR coating, and scattering long wavelengths into the solar cell. Leveraging its previous development of high performance flexible solar cells for Small Unmanned Aerial Vehicles, Agiltron proposes to develop nanostructured multi-functional top coatings for flexible thin film inorganic solar cells. The proposed top electrode can be readily applied on flexible thin film solar cells to achieve short-circuit current improvement by a factor of 25%. Phase I of this program is to demonstrate the technical feasibility through modeling, analysis, and experimentation.

Agiltron in collaboration with National Renewable Energy Laboratory (NREL) will develop a new class of high-efficiency and lightweight broadband inverted metamorphic multi-junction (IMM) solar cells for the uninterrupted flight missions of unmanned aerial vehicles (UAVs). The approach is closely coupled with Agiltrons extensive experience in high-transmittance broadband and wide-angle anti-reflective microstructures and NRELs significant progress in high efficiency IMM solar cells to push the cells conversion efficiency performance well beyond the current state-of-the-art. The novel solar cells will be transferred from thick, heavy, and stiff substrates to a thin, light and flexible support handle, thus meeting the NAVYs specific-power requirement. This novel solar cell technique has several unique advantages over conventional approaches, including high conversion efficiency, high specific power, wide incident angle acceptance, broad band operation, and high flexibility. The technical approach has been proven in Phase I through numerical analysis, simulations and experiments. The solar cell array module prototype will be designed, fabricated, characterized, and delivered to the Navy in Phase II.

A compact and effective 10-micron femtosecond laser with pulse duration <500fs and repetition rate of 100Hz or smaller is desirable by DOE for seeding CO2 ultrafast laser systems to improve the stability, reliability and efficiency in generating 10-micron laser from GW up to 100TW peak power, which is irreplaceable in driving an accelerator for particle beam generation due to the efficiency proportional to the square of the laser wavelength. Agiltron proposes a fiber based ultrafast 10-micron seed laser that can provide the required specifications and high performance. Its success will directly benefit DOEs compact proton and ion sources. The innovative technology can be used for ultrafast laser generation over the whole mid-IR range, and speed up the development of mid-IR laser applications.Agiltron, Inc. has successfully completed all tasks and demonstrated the feasibility of a fiber based 10-micron ultrafast laser in Phase I of the Program. We built a mode-locked fiber laser that generated < 400fs ultrafast laser pulses and successfully controlled the repetition rate to be the required 100Hz. Using this mode-locked laser, we demonstrated the feasibility of parametric femtosecond laser generation based on frequency down conversion. The experimental results agree with our simulation results. The investigation results of Phase I will be used to optimize the design of the laser system and build a fully functional prototype for delivery to the DOE in the Phase II program. The prototype development in Phase II program will be in the collaboration with Professor Chandrashekhar Joshi, the leader of UCLA Laser-Plasma group. Prof. Joshi discovered a new mechanism for generation of monoenergetic proton/ion beams: Shock Wave Acceleration in a near critical density plasma and demonstrated that high-energy proton beams using CO2 laser driven collisionless shocks in a gas jet plasma, which opened an opportunity to develop a rather compact high-repetition rate ion source for medical and other applications which could be significantly cheaper than that based on RF acceleration. We propose an output energy >1 J, one order of magnitude higher than the DOE original requirement. The performance of the prototype will be tested at UCLA by directly seeding the CO2 laser system driving an accelerator.
