Abstract

We experimentally uncover abnormal synchronization patterns in a breathing-soliton fiber laser, extending far beyond the classical Arnold’s tongues. By tuning intracavity loss, we map the synchronization between breathing frequency and cavity repetition rate, uncovering unexpected leaf-like and ray-like structures with internal holes—signatures of quasiperiodic dynamics. Supported by numerical modeling, these results provide the first experimental evidence of longpredicted complex synchronization geometries. Our findings establish breathing-soliton lasers as a versatile platform for exploring nonlinear synchronization in photonics and open new routes to control, stabilize, and harness dynamic behaviors in ultrafast optical systems.
