A method for synchronizing an etalon to a preselected set of optical frequencies includes the step of generating a transmission spectrum for an etalon having a characteristic free spectral range that is a function of its effective length. The optical frequencies for the transmission spectrum are provided by two optical reference frequencies such as produced by a first and second frequency locked laser. The effective length of the etalon is set in relation to the optical reference frequencies.

Méthode de synchronisation d'un étalon avec un ensemble présélectionné de fréquences optiques. Comprend la production d'un spectre d'émission pour un étalon ayant un intervalle spectral libre caractéristique dépendant de sa longueur efficace. Les fréquences optiques du spectre d'émission sont constituées de deux fréquences optiques de référence produites par exemple par un premier et un deuxième lasers à verrouillage de fréquence. La longueur efficace de l'étalon est établie par rapport aux fréquences optiques de référence.
