Uma equipe de pesquisa internacional desenvolveu uma estrutura matemática única que explica o comportamento rítmico incomum de pulsos de laser respirantes. O avanço une, pela primeira vez, dois regimes de dinâmica de laser anteriormente separados.

Pesquisadores, incluindo a Dra. Sonia Boscolo da Aston University, publicaram suas descobertas na Physical Review Letters. O estudo mostra que os ciclos de respiração rápidos e lentos em lasers ultrarrápidos surgem de processos físicos relacionados, em vez de mecanismos distintos. Os respirantes acima do limiar oscilam rapidamente e se travam na cavidade, enquanto os respirantes abaixo do limiar evoluem lentamente por meio de comutação Q combinada com a formação de sólitons.
