Résumé
Optical frequency combs have extremely high measurement accuracy for laser frequencies in the optics range, up to an order of approximately ~10�]11. However, this technique requires narrow linewidth and frequency stable laser sources. The first set of measurement results we carried out were with an optical frequency comb in the 1550 nm range. These measurements are focused on the frequency stability, linewidth of the laser source and the absolute value of the optical frequency. Two wavemeters for optical communications were calibrated using the previous results. Furthermore, the stabilization of a laser diode in the Rb atomic absorption at 780 nm is presented. This source is expected to be used as calibration standard for wavemeters and as reference laser for optical clocks and frequency combs comparison.
