Abstract

Using a highly accurate polarimetric method, we determine the gyration tensor component g11 for Ca3Ga2Ge4O14 (CGG) crystals. For this aim we employ a single-wavelength high-accuracy polarimeter and eliminate the main systematic errors of our polarimetric measurements. A calculation technique based on the polarizability theory for optical activity (OA) is applied to derive optical rotatory power (ORP) for the CGG. A comparison of the observed and calculated OA parameters confirms the validity of our theoretical calculations. Dispersions of both the ordinary and extraordinary refractive indices and the ORP are calculated.
