Paper Abstract

Ytterbium-doped Large Pitch Fibers with very large mode areas are investigated in a high power fiber amplifier configuration. An average output power of 294 W is demonstrated, while maintaining robust single-mode operation with a mode field diameter of 62 μm. Compared to previous active large mode area designs the threshold of mode instabilities is increased by a factor of about 3.
