Abstract

Mg-doped lithium niobate (LiNbO3) has found uses in SHG and optical parametric oscillator applications based on its ability to handle high optical power densities without exhibiting the photorefractive damage found in the undoped material.1 Although it is known that the photoconductivity of this material is greatly enhanced by the doping process,2 the physical origin of this effect is not well understood. In applications where tuning of the indices via the electrooptic effect is required, this can lead to space- charge fields which counteract the applied electrical field. Prior measurements of the dark conductivity were made at temperatures well above those used in actual use, and the role of the Mg ion in the photoionization process was not explored.3 In this paper, we discuss the physical origin of this effect based on new measurements of the conductivity in Mg-doped LiNbO3 and a 1-D model of the charge transport process.
