The Navy requires high power laser sources that can provide multi-Watt output power levels in the mid-infrared for optical countermeasures of anti-ship missiles. Current state of art laser transmitters, consisting of diode-pumped solid-state lasers andoptical parametric oscillators, have demonstrated the required optical power and wavelength in the mid-infrared spectral region. However, these la ...

Significant cost reductions are needed in the cost of IRCM laser transmitters to improve their affordability and adoption. A COTS based laser electronics module that can be tightly integrated with a low cost mid-infrared laser will be developed andenvironmentally tested in the Phase I effort. In addition, capability for advanced waveform generation will be incorporated into the electronics provi ...

We propose to build a novel eyesafe fiber laser source capable of operating over the 20-100 kHz repetition rate range. Using a combination of COTS technology from the telecom industry and amplifier designs based upon recent developments at Naval ResearchLabs, the source will deliver 7-10 Watts while maintaining pulse duration

The Navy requires high power laser sources for of eye-safe range-gated imaging LADARs. Conventional eye safe laser sources using diode-pumped solid-state laser (DPSSL) and optical parametric oscillator (OPO) technologies have difficulty to meet thepackaging requirements and to operate with constant pulse width at variable repetition rate. In Phase I of this project, Aculight has demonstrated al ...

Aerosol particles play an important role in visibility, acid deposition, climate, and human health, although large uncertainties remain in quantifying their impacts which depend on their chemical composition and atmospheric transformations. An innovativeaerosol mass spectrometer has been recently designed to fill a critical need for size-resolved, quantitative chemical composition data on aerosol ...

The Leaning Airbeam Shipboard Arrestment System (LASARST) is a radically different type of UAV recovery system for shipboard and unprepared land based operations. Although LASARST can also be used with LPD class vessels and small land based recovery areas,it is designed specifically for those vessels that have too small a deck area to capture the UAV in the `conventional' or current method (i.e. S ...

New technology is needed for the nondestructive detection and characterization of defects in aerospace structures, particularly those with complex shapes, that are used in high stress environments that accelerate degradation. Existing nondestructiveevaluation (NDE) techniques, based on ultrasonics, eddy-currents, and x-radiography do not have the capabilities needed for real-time defect detection ...

ALPHATECH proposes a novel approach for prognostics, diagnostics, and health management (PHM) of interconnected aircraft subsystems, using hybrid reduced-order prognostic models and extensions to existing diagnostic FMECA analyses. This technology will beapplied at the area reasoner level of the aircraft, and tailored to the Propulsion System. In close collaboration with our partner, Rolls-Royce ...
