| Abstract: |
Irradiation of 5% magnesium-doped lithium niobate crystals (LiNbO 3 :Mg) with high-energy, low-mass 3 He ions, which are transmitted through the crystal, changes the domain reversal properties of the material. This enables easier domain engineering compared to non-irradiated material and assists the formation of small-sized periodically poled domains in LiNbO 3 :Mg. Periodic domain structures exhibiting a width of ≈520 nm are obtained in radiation-damaged sections of the crystals. The ferroelectric poling behavior between irradiated and non-treated material is compared. |
