We review our recent work on the use of genetic algorithms to control non-stationary nonlinear wave dynamics in ultrafast fibre lasers, including the generation of breathing-soliton dynamics with controlled characteristics, the disclosure of the fractal dynamics of breathers, and the generation of rogue waves with controlled intensity.

We demonstrate for the first time the generation of broadband tunable and synchronized pulses exceeding the microjoule level using the new concept of fiber optical parametric chirped-pulse oscillation (FOPCPO). The oscillator is based on a collapsed-ends photonic crystal fiber pumped in the normal dispersion regime by a fiber laser.

We unveil a strategy for configuring mode-locked fiber lasers by means of a tunable bandpass filter, which allows multi-pulse structures to be generated without distortions in their intensity profiles, with significantly reduced pumping power levels.

An overview of dissipative soliton resonance in fiber lasers
Florent Bessin, François Sanchez, Andrey Komarov, Georges Semaan
Université d'Angers, France
Because of the pulse energy quantization in fiber lasers, it is of great importance to find effective
ways to increase the pulse energy directly from a fiber laser. An efficient technique is based on the dissipative
soliton resonance (DSR) effect. The DSR manifest as a square pulse with constant peak power and a linear
increase of both the pulse energy and duration for increasing pumping power. In practice, DSR is favoured
with the use of long cavities. In this communication we propose an overview of DSR in fiber lasers including
general theoretical approaches together with the most recent relevant experimental results

Optical frequency combs are applicable across many fields, especially in metrology. Through accounting for field polarization, the spontaneous symmetry breaking of vector temporal cavity solitons and combs in Kerr Fabry–Perot resonators is presented. This work can improve the generation of frequency combs through its control on the maximum number of soliton-pairs in a round trip and reveals the interesting phenomenon of dominant polarization conformity across all soliton-pairs in the cavity.
