Narrow linewidth, 100 W cw Yb^3+-doped silica fiber laser with a point-by-point Bragg grating inscribed directly into the active core - Nemanja Jovanovic, Mattias Åslund, Alexander Fuerbach, Stuart D. Jackson, Graham D. Marshall, Michael J. Withford
We report on the power scaling to 103 W of a 1.1 μm continuous-wave Yb^3+-doped silica fiber laser incorporating a point-by-point (PbP) fiber-Bragg grating inscribed directly into the active core using 800 nm femtosecond laser pulses. The spectrum of the laser exhibited a narrow linewidth ... [Opt. Lett. 32, 2804-2806 (2007)] [Optics Letters]
