Abstract
a. Elément sélectif pour sélecteur de mode pour laser. b. Dans un sélecteur de mode du type Michelson constitué d'une séparatrice S1 et de deux miroirs dont l'un est M 1 , on monte dans un de ses bras un élément sélectif, par exemple en remplaçant un des miroirs du premier Michelson (ou les deux) par un second Michelson constitué d'une séparatrice S2 et de deux miroirs M2 et M3, dont la différence de chemin optique est dans un rapport voisin de la dizaine avec la différence de chemin optique du premier Michelson. c. Lasers à bande large.
