REDONDO BEACH, Calif., May 15 -- Northrop Grumman Corp. said it has developed a fiber amplifier that produces a record output of 155 watts from a slender optical glass thread. The energy emerges as infrared light with a single polarization. "This demonstration is a big step forward in the scaling of fiber lasers to high power," said Jackie Gish, technology product area manager for Northrop Grumman Space Technology. "Our approach is scaleable, and if you were to coherently combine a number of such fibers, as we’re starting to do, you begin to reach significant laser power levels.
