Abstract
Laser pour la production d'impulsions de longueur d'onde prédéterminée, comportant au moins deux groupes de réflecteurs, un milieu laser stimulable et un dispositif de stimulation dudit milieu. Le premier groupe de réflecteurs est un interféromètre I, qui comporte un diviseur 1, 2 inséré sur le trajet du faisceau provenant de la marche du faisceau laser pour produire deux faisceaux partiels, un groupe de réflecteurs 4, 5 réfléchissant les faisceaux partiels sur le diviseur, et un dispositif 3 de variation du rapport des longueurs des trajets optiques des faisceaux partiels entre le diviseur et le groupe de reflecteurs.
