Abstract
The pulse dynamics of a self-starting Yb-doped fiber Mamyshev oscillator without external seed pulses or additional starting arms is demonstrated experimentally. Multiple dynamic patterns of pulses, including single pulses, bound-state pulses, and harmonic mode-locking pulses, are observed at different pump powers and filter spectral separations. The generation and evolution of bound states have also been simulated by establishing the corresponding theoretical model. This is the first systematic theoretical and experimental study of the formation and evolution of bound states in Yb-doped Mamyshev oscillators. The numerical results are in excellent agreement with experiment results, providing validation of both the measurements and the numerical model.
