Abstract

We report on the power scaling to 103 W of a 1.1 μm continuous-wave Yb8+-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 11mm long periodically poled MgOiLiNbO3 crystal to generate 2.1W of green with an internal conversion efficiency of 10% at high power and 0.81%/W at low power.
