Abstract

We demonstrated a 97 W all-fiber picosecond master oscillator power amplifier seeding by an actively harmonic mode-locked Yb-doped fiber laser. The laser seed pulse duration was 7.7 ps at a 1.223 GHz repetition rate with a central wavelength of 1062 nm. In addition, by launching the amplified pulses into a 5 m long photonic crystal fiber, we obtained a 41.8 W supercontinuum covering the wavelength from 600 to 1700 nm with a 10 dB bandwidth of 1040 nm.
