Resumo: This article presents a review of a Frequency Comb based on an erbium-doped mode-locked laser at a wavelength of 1550 nm, where the self-reference method for identifying the two degrees of freedom, repetition and offset frequencies is explained; detailed how these frequencies are stabilized and how the spectral broadening is performed, generating supercontinuum signals to measure external continuous laser as a motivation for a better understanding of the importance of this equipment in the context of the next redefinition of the second in the optical domain.
