Description: We report on the power scaling to 103 W of a 1.1 μm continuous-wave Yb³⁺-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 that broadened to 260 pm at 103 W. The output was frequency doubled using an 11 mm long periodically poled MgO:LiNbO₃ crystal to generate 2.1 W of green with an internal conversion efficiency of 10% at high power and 0.81%/W at low power.
