| Research Abstract |
A novel refractomety method by using an optical frequency comb which generates continuas spectrum of coherent light over the visible range. By analizing a transmission spectrum of a Fabry-Perot cavity, refractive index of a medium between the cavity mirrors can be determined. The present experimental results for air-gapped cavity, the measurement uncertainty of refractive index is a few part of 10^<-5>.
