Rapporté par l'IA

Une équipe de recherche internationale a développé un cadre mathématique unique qui explique le comportement rythmique inhabituel des impulsions laser pulsantes. Cette avancée réunit pour la première fois deux régimes de dynamique laser jusqu'ici distincts.

Des chercheurs, dont le Dr Sonia Boscolo de l'Université d'Aston, ont publié leurs conclusions dans Physical Review Letters. L'étude démontre que les cycles de pulsation rapides et lents des lasers ultrarapides proviennent de processus physiques apparentés plutôt que de mécanismes distincts. Les pulsateurs au-dessus du seuil oscillent rapidement et se verrouillent à la cavité, tandis que les pulsateurs en dessous du seuil évoluent lentement grâce au déclenchement (Q-switching) combiné à la formation de solitons.
