Title: Method for bulk periodic poling of congruent grown ferro-electric nonlinearoptical crystals by low electric field

Abstract: A new method is proposed and demonstrated effectively in reducing thecoercive field and internal field in association with bulk periodicalpoling of the congruent grown ferro-electric nonlinear optical crystal. Byadequate doping with zinc oxide, the coercive field required for achieving180.degree. domain reversal and the internal field associated with thenon-stoichiometric point defects in undoped congruent grown ferro-electricnonlinear optical crystals can be reduced by an order of magnitude.
