Abstract
Interferometrical methods have long been a very precise way to measure optical wavelength. The development, since now almost 20 years, of highly stabilized laser sources has permit to undertake interferometric measurements of wavelength ratios to an accuracy level which was not accessible to the wavelength standard of the previous definition of the meter based on the value of the krypton orange line. Since October 20th 1983 the meter is defined as following : "Le metre est la longueur du trajet parcouru par la lumiere dans le vide en une duree de 1/299792458 de seconde."
