A 104.2 W supercontinuum spanning from 750 nm to beyond 1700 nm is generated by pumping a piece of home-made seven-core photonic crystal fiber with a 141.6 W picosecond fiber laser. The evolution of the output spectrum is investigated in detail with the increase of the picosecond laser power. The feasibilities of broadening the spectral range and scaling the output power for the supercontinuum source based on the seven-core photonic crystal fiber are analyzed and discussed. The research results will make a contribution to the further development of high-power supercontinuum source.
