Abstract

We present our site-selective spectroscopic studies on Er3+ doped nearly stoichiometric lithium tantalate (LiTaO3) and compare the results with earlier studies performed on the same dopant in the isostructural lithium niobate host. We present our results in terms of the number and spectroscopic characteristics of the incorporation sites. Overall, the sites found in LiTaO3 closely resemble in their behavior the ones found in LiNbO3 such that the conclusion about the nature of the site drawn in the latter host can be transferred to LiTaO3 as well.
