High repetition rate picosecond large mode area Yb doped fiber amplifier with mo

We demonstrate a diode-pumped master-oscillator/fiber-amplifier (MOFA) system consisting of a passively SESAM mode-locking Nd:YVO4 laser and a Yb-doped large-mode-area fiber amplifier, which generates total average power of 24.4 W at 1 064 nm center wavelength, 91.5 MHz repetition rate, and 21.9 ps
