Abstract

L'invention a pour objet un laser à plusieurs longueurs d'onde et à commutation rapide. Il comprend un réflecteur dispersif du genre de ceux qui renvoient sur lui-même un faisceau de lumière ayant une certaine incidence seulement pour une longueur d'onde déterminée qui dépend de ladite incidénce et il est caractérisé en ce qu'il comprend, intercalé entre un milieu amplificateur et le réflecteur dispersif, un moyen pour modifier séquentiellement l'incidence. Application à la réalisation de lasers servant notamment au dosage des polluants dans l'atmosphère.
