Noise-like pulse generation from a Ho-doped fiber laser based on nonlinear polarization rotation

摘要

In this letter we have demonstrated, an all-fiber Ho-doped fiber laser working on the noise-like pulse regime based on nonlinear polarization rotation (NPR). The 18.3 nm spectral bandwidth was obtained at the central wavelength of 2133 nm, with the maximum output power of 68.6 mW. To the best of our knowledge, it is the first Ho-doped fiber laser working in noise-like pulse regime. The evolvement among different pulse regimes was also investigated in this experiment.
