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