Abstract

We have experimentally observed a new kind of ultra-broadband high-energy dissipative soliton pulse in a compact erbium-doped all-fiber laser with long cavity length and large net normal dispersion. The pulse characteristics and evolution processes are quite distinct from those reported in previous literatures. Remarkablely, the spectral width of pulses increases whereas the pulse duration decreases with the increase of pump power, so the pulse energy and peak power increase monotonically. At the maximum available pump power of 1.1 W, this fiber laser delivers pulses with the 3-dB bandwidth of about 73 nm, the pulse duration of about 56 ps, the pulse energy of about 200 nJ, and the peak power of about 3.5 kW. The proposed all-fiber laser can find important potentials in high-energy pulse generation and amplification systems.
