    Ytterbium-doped photonic-bandgap fiber sources operationg at the long-wavelength edge of the ytterbium gain band are being investigated for high power amplification. Artificial shaping of the gain spectrum by the characteristic distributed filtering effect of the photonic bandgap enables spontaneous-emission-free power svaling. As high as 167 W power and 16 dB saturated gain at 1178 nm have been demonstrated
