Abstract

L'invention concerne un procédé permettant de faire fonctionner un dispositif à laser (1), au moyen duquel un peigne de fréquences optique peut être stabilisé, les fréquences des modes de ce dernier pouvant être décrites par la formule fm= m x frep + f0, frep étant un espacement de mode, f0 une fréquence de décalage et m un nombre naturel. Au moins un signal (S1, S2, S3, S4) est déterminé, lequel est corrélé à une valeur réelle d'un degré de liberté (F), le degré de liberté (F) étant une combinaison linéaire composée de la fréquence de décalage f0 et de l'espacement de mode frep du peigne de fréquences. La valeur réelle du degré de liberté (F) dans une plage de capture (F) prédéfinie d'une deuxième unité de contrôle (40) est ajustée sur la base du signal au moyen d'une première unité de contrôle (10). Dès que la zone de capture (ΔFCapture) de la deuxième unité de contrôle (40) est atteinte, la deuxième unité de contrôle (40) est activée et la valeur réelle est réglée sur une valeur théorique (FThéorique) à l'aide de la deuxième unité de contrôle (40).
