| contents | The stability of optical solitons is a crucial factor in various applications. This work reveals a novel stable multipulse soliton attractor in fiber lasers. The attractor represents a bound state of multiple solitons, pulling other dynamical states toward itself. By introducing a polarization-maintaining fiber (PMF), the enhanced birefringence in the cavity induces the differential group delay (DGD) between the polarization components of the pulse, leading to soliton splitting and, ultimately, the formation of multi-soliton states. These multi-solitons, affected by intracavity nonlinear and dissipative effects, form attractors consisting of one to seven soliton pulses. Through a combination of experiments and numerical simulations, we systematically investigate the robustness and dynamical behavior of the multipulse soliton attractors. In this context, we analyze disturbances introduced by "rogue" solitons with different frequencies and conduct a comprehensive study of their interaction with the multipulse soliton attractors. The results show that the multipulse soliton attractors are structurally stable and highly resistant to external disturbances, highlighting their potential for high-precision fiber lasers and advanced multipulse systems. |
