Summary
Numerical simulations reveal dissipative solitons in fiber lasers with anomalous dispersion. These solitons exhibit complex, oscillating pedestals, leading to multistability and asymmetric structures.
Area of Science:
- Physics
- Optics
- Nonlinear Dynamics
Background:
- Passive mode locking in fiber lasers is crucial for generating ultrashort pulses.
- Anomalous dispersion regimes can support unique soliton behaviors.
Purpose of the Study:
- To investigate the formation and properties of dissipative solitons in anomalous dispersion fiber lasers.
- To analyze the structural complexity and stability of soliton pedestals.
Main Methods:
- Numerical simulations of passive mode locking in fiber lasers.
- Analysis of soliton structures and spectral properties.
Main Results:
- Discovery of dissipative solitons with powerful, oscillating pedestals.
- Observation of complex spectral structures arising from pedestal oscillations.
- Demonstration of soliton multistability with varying pedestal structures.
- Identification of asymmetric, moving pedestals relative to symmetric ones.
Conclusions:
- Dissipative solitons in anomalous dispersion fiber lasers exhibit complex, multistable behaviors.
- Pedestal structure significantly influences soliton properties and spectral characteristics.
- Asymmetric soliton dynamics can emerge under specific nonlinear-dispersion regimes.
