Abstract :
High-power, high-efficiency ytterbium-doped solid-core photonic-bandgap fiber amplification at the long-wavelength edge of the Yb gain band is reported. Amplified-spontaneous-emission-free, 30 W non-polarized and 25 W linearly-polarized 1178 nm outputs have been achieved with <58% slope efficiencies.
