Paper Abstract

A Michelson wavemeter was developed to test the accuracy and give traceability to the wavelength of external cavity diode lasers. These lasers were stabilized using a Littrow configuration and an iodine gas cell as frequency reference, and they will be used as light sources in the assembly of a new interferometric system for gauge block calibration. Previously, the uncertainty evaluation of the Michelson wavemeter with a Vernier counter had to be made, in which, as it is usual, the counting set starts and stops when the interference phases of the reference and unknown wavefronts coincide.
