Abstract: The experiment is reported an all-fiber super-broadband noise-like pulse mode-locked fiber laser. To broaden the spectrum of noise-like mode-locked pulse, we managed the nonlinear and dispersion in the cavity. The average dispersion parameter is in the smaller anomalous dispersion regime with 0.12 ps/nm/km in the 58m cavity. The experiment achieved a super-broadband noise-like mode-locked pulse from 1300nm to 1750nm, 20 dB bandwidth of 362nm and 3 dB bandwidth of 102 nm. The spectrum bandwidth of the noise-like pulse greatly exceeds the gain bandwidth of the EDF.
