Commercial-off-the-shelf (COTS) components may be used to reduce the cost of the laser electronics needed for mid-infrared lasers being developed for infrared countermeasures applications. The Phase II project will develop circuit designs for these laser electronics using COTS components and demonstrate these laser electronics can operate in military environments. The laser electronics will be v ...

Fiber coupled mid-infrared semiconductor lasers provide potential reduction in life cycle costs for tactical military systems compared to current lasers. The proposed work will investigate the stability of semiconductor lasers in military environments for reliable insertion into mid-infrared transmitting fiber optics. The overall project will demonstrate stable operation of a moderate power, mul ...

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 ...

Combining AED Corp. and its multi-disciplinary team's extensive and unique heavy fuel engine (HFE) hardware development experience with commercial-off-the-shelf (COTS) diesel engine components, a concept diesel engine demonstrator (CDED) will be designed. Configured to facilitate dyno test exploration of power density, heat rejection, and fuel efficiency, the lubrication, cooling, and supercharger ...

THE PROPOSED EFFORT WILL DEVELOP AN INTEGRAL STARTER/GENERATOR FOR SMALL TURBO JET ENGINES. THE STARTER CAN BE POWERED BY A 28 VDC BATTERY. THE LENGTH OF THE STARTER WILL BE 2.5 - 3" AND THE 0.D. WILL BE 2.5". THE STARTER WILL BE ABLE TO GENERATE 190 OZ-IN OF PEAK TORQUE TO ACCELERATE THE TURBINE TO 50 KRPM. AFTER THE ENGINE RUNS ABOVE SUSTAINING SPEED THE ELECTRONIC CONTROL WILL SWITCH FROM THE S ...
