摘要

We report on mode-locked thulium-doped fiber lasers with high-energy nanosecond pulse, relying on the transmission semiconductor saturable absorber (SESA) and carbon nanotubes (CNTs-PVA) film, separately. Meanwhile, a section of SMF-MMF-SMF fiber structure multimode interferometer with transmission peak wavelength of ~2003 nm was used as a wavelength selector to fix the laser wavelength. When the SESA acted as SA, the mode-locked fiber laser has maximum output power of ~461 mW with pulse energy of ~0.14 μJ and pulse duration of ~9.14 ns. In CNTs-film based mode-locked fiber laser, stable mode-locked pulses with the maximum output power of ~46 mW, pulse energy of ~26.8 nJ and pulse duration of ~9.3 ns were obtained. To the best of our knowledge, our experiments demonstrated the first 2 μm region “real” SA-based dissipative soliton resonance with the highest mode-locked pulse energy from “real” SA-based all-fiberized resonator.
