Electro-optic properties of LiKSO4 and LiK1−x Rbx SO4 crystals
Résumé
The electro-optic properties of LiK1-xRbxSO4 for x varying between 0 and 0.50 were investigated by an ac modulation method based upon the S´enarmont arrangement. The electro-optic coefficient rc, and for the first time the coefficients r41 and r51 were determined with good accuracy in pure LiKSO4 around room temperature at a wavelength of 633 nm. The frequency dependence of the electro-optic coefficient rc was measured in the frequency range from 1 kHz up to 1MHz. The values of the factor of merit n3e rc of the mixed crystals LiK1-xRbxSO4 were obtained for the first time, for the concentrations x D 0:05, 0.10, 0.20, and 0.50. The electrooptic properties are shown to be affected by the random presence of the rubidium ions in this disordered system.
