Abstract
Abstract
We experimentally and theoretically investigate the noise-like pulse (NLP) generation in a nonlinear polarization rotation-based mode-locked Ho-doped fiber ring laser, which can optionally operate in the dual-wavelength regime. By carefully changing the pump power and polarization state, the dual-wavelength NLP regime at 2041.9 and 2083.3 nm is finally achieved, which corresponds to a pulse energy of 11.84 nJ and a pulse duration of 849 fs. It is believed to be the first report on the dual-wavelength NLP operation from the previously reported Ho-doped fiber lasers.
