摘要

A new method is proposed and demonstrated effectively in reducing the coercive field and internal field in association with bulk periodical poling of the congruent grown ferro-electric nonlinear optical crystal. By adequate doping with zinc oxide, the coercive field required for achieving 180° domain reversal and the internal field associated with the non-stoichiometric point defects in undoped congruent grown ferro-electric nonlinear optical crystals can be reduced by an order of magnitude.
