High-energy, multi-spectral laser for surf-zone mine countermeasures

"CTI proposes a high efficiency, extremely compact, multi-band laser source suitable for use in a beach and surf-zone imaging system. The transmitter will utilize low-risk laser components in a novel device geometry that permits the development of veryhigh wall plug efficiency transmitters with minimal cooling requirements. Additionally, the multi-band imager can be configured for polarization discrimination allowing more detector degrees of freedom. This feature enables the development of amulti-discriminant sensor for improved mine countermeasures. The proposed device is based on demonstrated CTI achievements in the area of solid-state lasers resulting in a low-risk Phase I/II program with a clear path to future production of minimal cost,turn-key, military hardware. At the end of Phase II a useful, multi-band device will be delivered to the Navy. This work will also fund development of an enabling technology that can impact a variety of fields including remote sensing, science andmedicine. High electrical efficiency, visible and short-wave infrared, pulsed laser sources are needed for a variety of applications including: detection and imaging, altimetry and ranging, terrain mapping, designation, search and rescue beacons, surgery,photodynamic therapy and cosmetic skin repair."
