Compact, Short-Pulse Laser Source for Active Imaging Systems

73137S03-IFuture active imaging systems for national security applications require compact, rugged, and efficient short-pulse laser sources that can operate over a wide-repetition-rate range. These systems can generate high-resolution topographical maps, which can help detect the proliferation of weapons of mass destruction. However, to achieve adequate range and resolution in airborne and space-borne systems, the laser sources must have short pulse duration, high repetition rate, and higher power than can be currently obtained with conventional laser technology. This project will develop a short pulse, high power, high-repetition-rate laser source based on innovative, fiber amplifier technology. The approach will make use of many components developed recently for the telecommunications industry. The all-fiber-based laser source will be efficient, compact, and reliable. Phase I will: (1) build and deliver a packaged, low-power seed source that exceeds all specifications in the solicitation; (2) develop a design for a high-power amplifier to be delivered in Phase II; and (3) perform low-power experiments to validate the design. Commercial Applications and Other Benefits as described by awardee: An all-fiber-based laser source should find use in a variety of military applications. Commercial applications include a laser source for medical diagnostics and instruments for industrial processing.
