Abstract

Photorefractive damage, optical absorption, photoconductivities, and photogalvanic currents of stoichiometric LiNbO<sub>3</sub> single crystals with different Mg doping levels have been investigated. Nominally pure stoichiometric LiNbO<sub>3</sub> shows lower photorefractive damage resistance than congruent crystal; however, stoichiometric crystals doped with MgO of more than 1.8 mol. % exhibit no measurable photorefractive damage at 532 nm to intensities of as much as 8 MW/cm<sup>2</sup> . This remarkable damage resistance can be attributed not only to increased photoconductivity but also to decreased photogalvanic current. Stoichiometric Mg:LiNbO<sub>3</sub> also demonstrates the shortest absorption edge, 302 nm, and a single-domain nature with low scattering losses.
