Abstract

A new method for measurements of values of individual linear electrooptic coefficients and their temperature dependencies is proposed. In the approach, both the electric-field-induced changes with temperature in the crystal birefringence and the temperature dependence of the ordinary and extraordinary indices are taken into consideration. To measure the changes in the electric-field-induced birefringence the dynamic polarimetric technique was employed (see, e.g. Ref. [1]). The method was applied for linear electrooptic coefficients r113 and r333 and their intrinsic counterparts. Our measurements were performed within the temperature range 25oC - 200 oC for samples of stoichiometry approximately 49.3%. Contrary to the results obtained for the coefficient r222 [2], we found r113 and r333 to be significantly temperature dependent. The changes in r113 and r333 are stronger than those obtained by interferometric means and reported for the same coefficients in Ref. [3], however, in Ref. [3] the stoichiometry of samples has not been indicated.
