78830 The Department of Energy requires improved measurement techniques to quantify trace gas species in the atmosphere, in order to achieve further understanding of the formation of aerosols and their role in climate change. This project will combine a novel, ultra-sensitive, photo-acoustic detection technique with a high power, widely tunable mid-infrared laser source to enable rapid, sub-part- ...

The DoD requires new sources of eye safe, short pulse, laser radiation to enable the next generation laser radar (LADAR) seekers. Conventional eye safe laser sources using diode-pumped solid-state laser (DPSSL) and optical parametric oscillator (OPO) technologies have difficulties to meet the packaging requirements and to operate with constant pulse width at variable repetition rate. Also, the e ...

Fiber coupled mid-infrared and infrared semiconductor lasers provide potential technology for proactive infrared countermeasures systems, potentially reducing life cycle costs for these tactical military systems compared to current lasers. Research will be conducted to explore the feasibility of developing low loss infrared transmitting chalcogenide glass fiber optics. The proposed work will als ...

First generation mid-infrared lasers contribute to the prohibitively high life cycle cost of infrared countermeasures systems, precluding their broad application in helicopters. We propose to develop a fiber amplifier-based IRCM laser transmitter that will contain all optical beams within optical fiber, eliminating adjustable, discrete, optical mounts, to significantly increase the laser's MTBF. ...

78807 The remote detection of chemical signatures for nuclear proliferation, requires a pump laser capable of driving a tunable ultraviolet light source. The pump laser must be compact and efficient, and produce a very high quality beam. This project will build a pump laser with a relatively new laser material, Yb:S-FAP, developed by the DOE at Lawrence Livermore National Laboratory. Yb:S-FAP a ...

The purpose of this program is to develop a compact and efficient ultraviolet laser system for use in space-based uv-Raman instruments. The basis for this system will be a modulated diode seed laser followed by a fiber amplifier which is frequency-quadrupled to generate uv light at 245nm. The unique combination of a compact and efficient fiber amplifier with efficient harmonic generation will pro ...

DESCRIPTION (provided by applicant): In a novel technological breakthrough in neural stimulation, our collaborators at Vanderbilt University have developed a new modality that uses low intensity pulsed infrared laser light instead of electrical energy to elicit compound nerve and muscle potentials. Optical stimulation can induce spatially precise, highly controlled and artifact-free action potenti ...

This Small Business Technology Transfer (STTR) Project will result in the generation of a new nano-technology specifically tailored to increase the efficiency of the boiling processes used in heat exchangers and electronics cooling hardware. Unlike traditional flat surfaces and previously investigated microporous surface (MPS) coatings, homogeneous nanoporous surfaces (NPS) offer a simple-to-manuf ...

This Small Business Technology Transfer (STTR) Phase I project develop a new generation of proton exchange membrane (PEM) technology. The proposed project will investigate processing techniques for synthesizing polyphosphazine membranes, which are hydrogen bonded to form supramolecules. Such supramolecular interactions can be fully miscible or self organized polymeric backbones to form two or more ...

DESCRIPTION (provided by applicant): Celiac disease is an autoimmune digestive disorder in which intestinal lesions develop in genetically susceptible individuals in response to the ingestion of specific seed storage proteins found in cereal grains. The only treatment is strict adherence to a diet from which the offending grains have been eliminated. Therefore, considerable research has been devot ...
