All-fiber dissipative soliton laser based on single-walled carbon nanotube absorber in normal dispersion regime

We demonstrat a compact Yb-doped fiber (YDF) laser based on the single-walled carbon nanotube (SWCNT) wall-paper absorber. It can operate at dissipative solitons mode-locking state stably for more than 24 h at the room temperature, and there is no significant degradation of the laser spectra, pulse train, and output power. The spectral bandwidth of the mode-locked pulses varies from 0.35 to 0.64 nm depending on the level of the pump power. The amplified pulses possess single pulse energy of 3.87 nJ and pulse duration of 421.9 ps. The repetition rate is ∼23.83 MHz. The largest output power reaches 92.3 mW.
