Paper Abstract

Mode-locked regimes of Yb-doped fiber laser with the photonic bandgap fiber (PBF) used for dispersion compensation in the laser cavity are studied using numerical modeling. The impact of the PBF's third-order dispersion on the dynamic instabilities of mode-locked regimes is elucidated. It is demonstrated that the instabilities leading to multi-period pulsing results from destabilization of resonant sidebands associated with dispersive waves. Novel type of stretched-pulse multi-period pulsing regime with symmetry-breaking features is identified. It is demonstrated that third-order dispersion suppresses the multi-period instabilities in the stretched-pulse regime. From the analysis of the spectral sidebands, we conclude that the suppression mechanism relies on resonant coupling of the phase-velocity matched and group-velocity matched dispersive waves with the main pulse spectrum.
