WebDec 22, 2024 · We report the experimental observation of evolving phenomenon of a split multi-wavelength bright-dark pulse in the nonlinear amplifying loop mirror (NALM)-based mode-locked thulium-doped fiber laser (TDFL) with a figure-eight configuration. Bright-dark pulse with 10 wavelengths was successfully obtained at the pump power of 3 W. WebJul 1, 2024 · The reason behind is the difficulties to design the fiber laser cavity that fulfil the dark pulse generation conditions. Based on the NLSE, the dark pulse can be generated in a well govern dispersion and highly nonlinear conditions.
