Mode-locked lasers exhibit complex nonlinear dynamics. Precise observation of these dynamics will aid in the understanding of the underlying physics and provide new insights for laser design and applications. The starting dynamics, from initial noise fluctuations to the mode-locking regime, have previously been observed directly by time-stretched transform-based real-time spectroscopy. However, the regime transition dynamics, which are essential processes in mode-locked lasers, have not yet…

Intelligent control of mode-locked femtosecond pulses by time-stretch-assisted real-time spectral analysis

The complex, repeatable transition dynamics of the spectrum broadening of femtosecond pulses, including five middle phases, are revealed, which provides deep insight into ultrashort pulse formation that cannot be observed with traditional mode-locked lasers.

Time-stretch probing of ultra-fast soliton dynamics related to Q-switched instabilities in mode-locked fiber laser.

Using the time-stretch technique, this work is able to trace the real-time evolution of the soliton bound state formation and mode-locking build-up in a mode-locked fiber laser and finds that the evolving patterns ofsoliton bound states are highly dependent on their initial conditions.

Real-time full-field characterization of transient dissipative soliton dynamics in a mode-locked laser

Dissipative solitons are remarkably localized states of a physical system that arise from the dynamical balance between nonlinearity, dispersion and environmental energy exchange. They are the most

Soliton explosions are among the most exotic dissipative phenomena studied in mode-locked lasers. In this regime, a dissipative soliton circulating in the laser cavity experiences an abrupt

Real-Time Observation of the Buildup of Soliton Molecules.

The first observation, to the best of the knowledge, of the entire buildup process of soliton molecules (SMs) in a mode-locked laser is reported and the evolution of pulses in the raised RO stage follows a law that only the strongest one can ultimately survive.

Real-time spectral interferometry probes the internal dynamics of femtosecond soliton molecules

Spectral interferometry images the formation, binding, and internal dynamics of optical soliton complexes as they propagated in a laser cavity and tracks two- and three-soliton bound states over hundreds of thousands of consecutive cavity roundtrips, implying that its dynamics may be topologically protected.

It is revealed that the appearing of the spectral sharp peaks with oscillation structures during the mode-locking transition is caused by the formation of structural dissipative soliton.

Raman rogue waves in a partially mode-locked fiber laser.

Dispersive Fourier transformation is used to measure single-shot spectra of Raman-induced noise-like pulses, demonstrating that for low cavity gain values Raman emission is sporadic and follows rogue-wave-like probability distributions, while a saturated regime with Gaussian statistics is obtained for high pump powers.
