Towards an all-fiber mode-locked Tm-doped Mamyshev oscillator

This work focuses on optimizing the pump power and tunable filter to achieve mode-locking operation in an all-fiber Mamyshev oscillator. Based on the Tm-doped Mamyshev oscillator, we have a clear understanding of the effect of pump power and wavelength of the bandpass filter on its operation mode, such as mode-locking, pulse splitting, multi-pulse train with random distribution and amplification of the seed. Our study provides valuable insights and directions for how to optimize the pump power and tunable filter to achieve mode-locking in a complex Mamyshev oscillator based on the existing non-mode-locking state.
