The optical properties of Tm-doped LiNbO<sub>3</sub> and LiNbO<sub>3</sub>:(MgO), especially within the <sup>3</sup>H<sub>6</sub> to <sup>3</sup>H<sub>4</sub> transition, have been studied. Differences in the absorption spectrum and particularly in the emission spectrum of Tm in both crystals are observed. New bands with different polarisation character appear in the MgO doped crystals, indicating the existence of Mg-perturbed Tm sites.
