Irradiation of optical damage resistant, magnesium doped lithium niobate crystals with fast, high-energy {sup 3}He{sup 2+} ions changes important material properties. In the interaction region, where the ions transmit through the material, the ferroelectric coercive field E{sub C} is diminished from 6.0 kV mm{sup -1} down to 5.0-5.4 kV mm{sup -1} after transmission of 41 MeV {sup 3}He{sup 2+} particles. This enables easier domain reversal in irradiated crystals compared to untreated material. Besides, large changes of the refractive index of the crystals on the order of 6x10{sup -3} are induced by the treatment. Moderate annealing treatments do not diminish {delta}n, but refresh the coercive field.
