Abstract
The defect structure of Mg-doped lithium niobate crystals was studied with varying Mg doping concentration by means of Raman scattering measurements. The Mg content dependences of both the frequency and damping of the two low est-frequency A(1)(TO) phonon modes were used to derive the Mg incorporatio n mechanism in the LiNbO3 lattice. Results indicated that Mg ions are locat ed on the Li site for low doping and then replace both Li and Nb ions for l arger concentration.
