摘要：

We report on the design and experimental investigation of a preferential gain photonic-crystal fiber with a mode-field diameter of 47 mu m. This few-mode fiber design confines the doping of Ytterbium-ions just to the center of the core and, therefore, promotes fundamental mode operation. In a chirped-pulse amplification system we extracted up to 303 W of average power from this fiber with a measured M-2 value of 1.4. (C) 2011 Optical Society of America
