Dark-ring cavity solitons in lasers with bichromatic injected signal

TL;DR

This paper theoretically demonstrates that broad area lasers with bichromatic injection can support complex spatial structures like dark-ring cavity solitons, domain walls, and labyrinthine patterns, expanding understanding of laser pattern formation.

Contribution

It introduces the concept of dark-ring cavity solitons in lasers driven by bichromatic fields, a novel pattern formation mechanism in laser physics.

Findings

Dark-ring cavity solitons can exist in broad area lasers with bichromatic injection.

Bichromatic driving induces domain walls and labyrinthine patterns.

Theoretical analysis predicts stable complex spatial structures in such lasers.

Abstract

We show theoretically that broad area lasers driven by a nearly resonant bichromatic field may support dark-ring cavity solitons as well as domain walls and labyrinthine patterns.
