In this paper, a nonlinear absorbing-loop mirror (NAbLM) is constructed in a polarization-maintaining (PM) version and applied in the all-normal dispersion (ANDi) regime, for the first time to our best knowledge. To investigate the properties of NAbL

A tunable continuum with multiwatt output power is demonstrated for the first time through the pumping of cascaded fibers by using a continuous-wave (CW) ytterbium fiber laser. The central wavelength of the output continuum can be tuned continuously
