Title

Multicore-fiber-based, high-power femtosecond CPA laser system with fast dynamic beam shaping capabilities

Abstract
We present a femtosecond laser system based on a 49-core, Ytterbium-doped fiber. Phase control of the individual beams enables fast beam-shaping up to the kHz frequency range at 150 W total average power after compression.
