Supporting data for “Unveiling dissipative soliton spectral-temporal dynamics in mode-locked fiber lasers”.

The supporting data for “Unveiling dissipative soliton spectral-temporal dynamics in mode-locked fiber lasers” involves corresponding figures and the original dataset in the thesis. The subfolders in the dataset zip file contain datasets from Chapter 3 to Chapter 9 of the thesis. In this thesis, we mainly focused on the exploration of the nonequilibrium dissipative soliton dynamics by utilizing the single-shot TS-DFT technique, involving the buildup and dissociation dynamics of stationary soliton molecules in a unidirectional mode-locked fiber laser; breathing soliton dynamics in a bidirectional mode-locked fiber laser involving breathing soliton explosions, breathing soliton molecule switching, and dynamics of breathing soliton pairs with nanosecond temporal seperation. Moreover, the collision dynamics of dissipative soliton molecules in a 1.5 μm dual-wavelength ultrafast fiber laser, and reconfigurable switching of optical soliton molecular complexes in a 2 μm ultrafast thulium fiber laser have also been explored. Further, the laser radiation of multiple optical solitons nonequilibrium evolution was revealed by utilizing NFT and real-time coherent homodyne detection methodology. During the experiment, the temporal information of pulses was detected by a 20 GHz photodiode (Agilent 83440C) and digitized by a 20 GHz real-time oscilloscope (Lecroy SDA 820Zi-B), while the optical spectrum was recorded by an optical spectrum analyzer (OSA, YOKOGAWA AQ6370D), and the real-time oscilloscope using TS-DFT simultaneously. The DFT branch was composed of a spool of dispersion-compensating fiber with -577 ps/nm/km dispersion and detected by a 12 GHz photodiode (New Focus 1544-B), with a single-shot spectrum resolution of 0.17 nm. Therefore, the supporting data from chapters 3 to 9 correspond to the experimentally detected OSA spectra and real-time recorded pulse information through TS-DFT to characterize the dissipative soliton evolution in mode-locked fiber lasers with different configurations and emitting wavelengths.
