| Research Abstract |
A spectroscopic system with ultra high resolution and with ultra high sensitivity was developed. In order to attain the ultra high resolution and the ultra high sensitivity, an optical frequency comb and a high finesse optical resonator were used, respectively. The system was designed and manufactured, and was applied to the Doppler free spectroscopy of naphthalene and iodine molecule. In the obtained spectra, even rotational lines were well resolved. The highest frequency resolution in the area of molecular spectroscopy, where the wide range frequency scan is necessary, is accomplished in this work.
