R&D100 2007 Entry: Mode-Filtered Fiber Amplifier

Description: SAND2007-1475P Mode-Filtered Fiber Amplifier: The capability of coiled fibers to dramatically increase the useful power produced by fiber lasers has led to fabrication of high-power, high-beam-quality lasers that are compact, rugged, and extremely efficient. Prior to this breakthrough, fiber lasers were thought to be restricted by fundamental physical limitations of the fiber to low output powers and pulse energies. This technology also received the Editor’s Choice Award for Most Enabling New Technology.
