Abstract
Power amplification of all-fiber Yb-doped double clad fiber (Yb DCF) amplifier seeded by all-normal dispersion mode locked Yb-doped fiber oscillator is reported. 21.8 W of amplified average power at 39 MHz repetition rate was obtained at pump power of 35 W corresponding to ~62 % pump to signal conversion efficiency. The single pulse energy of the amplified mode locked pulses was ~560 nJ. The spectrum of the pulses shows no serious distortion and ASE contribution on power amplification.
