Description

Irradiation of optical damage resistant, magnesium doped lithium niobate crystals with fast, high-energy 3He2+ ions changes important material properties. In the interaction region, where the ions transmit through the material, the ferroelectric coercive field EC is diminished from 6.0 kV mm-1 down to 5.0-5.4 kV mm-1 after transmission of 41 MeV 3He2+ 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 6x10-3 are induced by the treatment. Moderate annealing treatments do not diminish Δn, but refresh the coercive field
