Abstract
The polarized absorption spectra of Tm3+ ions in LiNbO3 and LiNbO3(MgO ) CryStalS, at 20 K, are presented. The Stark levels of the different multiplets up to 28000 cm-1 are identified. The results are consistent with C3 Symmetry for the rare-earth ions and a singlet (A) character for the lower Stark level of the ground state. Several transitions sho w additional structure, which indicates multi-site occupancy for the T m3+ ions. The effect of MgO codoping, which includes the appearance of new absorption bands, is also discussed.
