The Stationary Soliton Molecules Generation and Management in Tm-doped Mode-locked Fiber Oscillator

We present an investigation on the high-SNR stationary soliton molecules generation and its characteristics analysis in a Tm-doped nonlinear polarization rotation (NPR) mode-locked laser oscillator. By inserting a narrow band filter, we successfully improved the generated soliton molecules with signal-to-noise ratio (SNR) to above 80 dB. This value is the highest ever reported to the best of our knowledge. In addition, we also explored the details of the temporal and spectral evolution of the generated solitons while optimizing the related parameters, including pump power, waveplates, intracavity dispersion, and so on. Such stationary soliton molecules with many interesting features will find many applications in high-speed telecommunications and micro-processing.
