102W picosecond all fiber one-stage MOPA laser

We report a high power picosecond pulses all fiber, one-stage MOPA system. A passively mode-locked ytterbium-doped fiber laser was used as seed source. Average output power as high as 102W was obtained in 76 ps pulses at 18.6 MHz repetition rate at 1064 nm with bandwidth of 0. 5 nm.
