Pattern formation and competition occur in a nonlinear extended medium if dissipation
allows for attracting sets, independently of initial and boundary conditions. This intrinsic …

We revisit the model of the laser with feedback and the minimal nonlinearity leading to
chaos. Although the model has its origin in laser physics, with peculiarities related to the CO …

We revisit the laser model with cavity loss modulation, from which evidence of chaos and
generalized multistability was discovered in 1982. Multistability refers to the coexistence of …

Abstract Systems with delayed feedback can possess chaotic attractors with extremely high
dimension, even if only a few physical degrees of freedom are involved. We propose a state …

Current theoretical and experimental work on quasiperiodicity is reviewed in this tutorial.
The concept of universality and its relevance to experiments on nonlinear multifrequency …

Successive transitions from Hopf bifurcation to Shilnikov chaos and eventually to regular
spiking are observed in a laser with feedback on increase of a control parameter. Each one …

Times series obtained from dynamical systems can be converted into sequences of time
intervals between relevant events. We show that under quite general conditions time …

Les travaux précurseurs d'Ikeda ont marqué le début de l'exploration en optique des
systèmes dynamiques décrits par des équations différentielles non linéaires à retard …

A single mode CW semiconductor laser with an optoelectronic feedback gives a modulated
output, with a sharp frequency peak depending on the feedback delay. A theoretical model …

Publisher Summary This chapter discuses the dynamical instabilities and pulsations in
lasers. The laser instabilities are of interest in the research efforts. The characteristics of …
