  We demonstrate compression and shaping of few cycle pulses from a high
average power Ytterbium laser system. The pulses from a commercial 20 W, 100
kHz Yb laser system are spectrally broadened in two-stages using gas-filled,
stretched hollow-core fibers and then compressed and shaped in an acousto-optic
modulator-based pulse-shaper. The pulse-shaper allows for compression,
characterization, and shaping all in one system, producing ~10 fs pulses with
50 uJ of energy
