In this article, the authors identify clear explosion signatures in measurements of shot-to-shot spectra of a Yb-doped mode-locked fiber laser that is operating in a transition regime between stable and noise-like emission.Abstract:
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 structural collapse, but within a few roundtrips returns to its original quasi-stable state. In this Letter, we report on the first observation, to the best of our knowledge, of such events in a fiber laser. Specifically, we identify clear explosion signatures in measurements of shot-to-shot spectra of a Yb-doped mode-locked fiber laser that is operating in a transition regime between stable and noise-like emission. The comparatively long, all-normal-dispersion cavity used in our experiments also permits direct time-domain measurements, and we show that the explosions manifest themselves as abrupt temporal shifts in the output pulse train. Our experimental results are in good agreement with realistic numerical simulations based on an iterative cavity map.read more

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

TL;DR: 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.

Real-time full-field characterization of transient dissipative soliton dynamics in a mode-locked laser
TL;DR: In this paper, the spectral and temporal evolution of ultrashort dissipative solitons in a transient unstable regime with complex break-up and collisions before stabilization is studied.

All-normal-dispersion femtosecond fiber laser
