Tiivistelmä
We demonstrate the dramatic progress in Yb-doped spun tapered double-clad fiber amplifiers delivering up to 550 W of average power with single mode spatial profile and 50 ps pulses at 20 MHz repetition rate. The special geometrical architecture of the fiber enables the direct amplification of short pulses from tens of mW to hundreds of watt levels in a single amplification stage, leading towards the realization of a compact and highly efficient picosecond fiber-based laser system with excellent output spatial and temporal characteristics.
