Dual-wavelength polarimeter application in investigations of the optical activity of a langasite crystal
Abstract
A method of high accuracy polarimetry, which includes optical activity measurements systematic errors, was realized with dual-wavelength polarimeter for two wavelengths of 635 and 650 nm. Simultaneous measurements with neighboring wavelengths significantly improved the data processing, by increasing the amount of data to eliminate the systematic errors. For langasite crystal La3Ga5SiO14 we measured temperature dependence of the gyration tensor component g11. Our acquired value doesn’t exceed 0.47×10–5 and is much smaller than previous results obtained by different experimental methods. Results presented in this paper correspond well with the calculated optical rotatory power from crystal structure data and polarizabilities of the atoms.
