Abstract
We investigate UV photorefraction in Mg-doped LiNbO3 crystals. Strong UV ph otorefraction is achieved in highly Mg-doped LiNbO3 crystals with high two- wave mixing gain, fast response, and low noise. It is also demonstrated exp erimentally that so-called damage-resistant dopants such as Mg are damage r esistant only in the visible and that they will enhance photorefraction in the UV.
