Noise-Like Pulses Evolution in Mode-Locked Fibre Lasers
Soliton formation of mode-locked doped fibre lasers caused by balanced interactions between nonlinear effects and dispersions has recently been investigated extensively. In this project, we explored and simulated a special case that the formed soliton’s pulse width is so narrow that the spectral ban...
