Unconventional spatially coherent, wavelength selectable broadband visible-IR source for standoff electro-optic (EO) imagers , sensors, and countermea

In this SBIR Phase II project, first, we will develop a ready-to-use unconventional spatially coherent, wavelength selectable, high average power, broadband visible-IR source by leveraging the very promising and encouraging proof-of-concept results achieved at the Phase I stage. Such kind of source is realized by employing (1) a tunable, 3-dimensional, nanoengineered, high IR transmittance and high laser damage threshold IR waveguide, (2) a highly compact, and high average power pumping source, and (3) a novel optical configuration. Second, we will apply this innovative source to the following critically needed army applications: (1) highly effective and robust electro-optic (EO) active countermeasures, (2) long range standoff sensors that can be used to identify the chemical compositions of the remote target and surrounding environment in real time, and (3) highly effective broadband IR imagers and LADAR seekers that can have significantly increased penetration of fog/cloud/smoke and provide the information on both the geometric shape and the material composition of the target so that a higher target recognition accuracy can be achieved. Finally, we will commercialize this technology by pursuing both the military and civilian usages.
