Abstract Two kinds of noise-like pulse bunches are observed in an erbium-doped fiber ring laser for the first time. Picosecond- and submicrosecond-scale pulse bunches with energy of 0.32 nJ and 7.1 nJ, respectively, are generated and used in super-continuum generation. Using a 50-m dispersion-shifted fiber (DSF) a 20-dB bandwidth of over 750 nm is obtained.
