We present the results of a comprehensive electro-optic EO study of Sr0.61Ba0.39Nb2O6 at Lambda 633 nm. The experiments are conducted in the transverse field configuration, hence the effective linear EO coefficient r sub c is measured. Uniformly poled samples yield r sub c 230 or -20 pmV at 25 deg C and r sub c 1600 or - 150 pmV at 65 deg C. However, the EO behavior is found to substantially degrade when attempting domain reversal. Imaging a crystal through crossed polarizers during the reversal process shows a very non-uniform birefringence distribution in the vicinity of the original -c electrode face.
