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. ...

The future generation of both military and commercial diesel engines will operate at significantly higher temperatures and pressures than today's engines. The future combat system diesel engine operating parameters demand significant design improvement of in cylinder insulation. Increased cylinder pressure and reduced cooling requirements, heat energy recovery in the exhaust gas by turbo chargin ...

A high-power density, low specific heat rejection diesel engine design for traditional and hybrid future combat system (FCS) vehicle configurations is being proposed.
