Abstract
High-accuracy self-correction of air refractive index was demonstrated with simultaneous measurement of group and phase indices. Using precise detection of the pulse envelope and the carrier phase with an optical frequency comb interferometer, a method similar to the two-color correction method was applied, but using a light source in a single wavelength region. In this study, air refractive index correction was successfully demonstrated with standard deviation of 8.1 × 10−8 when the refractive index change was 0.7 × 10−6.
