Wavelength Agile Spectroscopic Sources Based on Quasi-Phase Matched Structures

Abstract

With the equipment requested in the associated DURIP proposal (DURIP Topic #4, same title as above) and the graduate student support requested herein, we envision several new avenues of research. The tunable, narrow bandwidth output of the injection seeded system will serve as a near-infrared spectroscopic source for imaging combustion products at Wright Patterson Air Force Base (WPAFB). The anticipated energy output (30 mJ, 10 ns pulses) will allow multi-point or line measurements that provide much better diagnostic information than the currently used single point methods. We also envision utilizing the source for atmospheric pollutant sensing in laser radar/differential absorption lidar sensors or in multispectral laser radar target identification systems. Exhaust plumes, even oil pipeline leaks, and targets hidden in foliage can be easily detected by such systems. The pulsed source permits retrieval of range information as well. Finally we suggest some fundamentally new methods of building and tuning wavelength agile sources based on QPM materials structures. One example is a single crystal frequency tripler.
