50 GHz, 100 fs pulses at 100 W average power from a burst mode, all-single mode, Yb-doped fiber laser system

Abstract

We present a uniquely simple laser integrated in strictly single-mode fibers, producing bursts of 100-fs pulses at 50 GHz repetition rate at 100 W average power. This allows material processing with high efficiency and precision in the ablation-cooled regime.
