摘要：

Raman microprobe spectroscopy measurements show, that in contrast to Er-idiffusion, Er-exchange process leads to significant change of the lattice vibration spectrum of LiNbO3. Therefore, our data allow to assume that the drastic suppression of parasitic upconversion in the Er-exchanged LiNbO3 are caused by multiphonon nonradiative decay of the 2(F-4(9/2)) state, providing fast nonradiative energy transfer to the (4)G(11/2) and O(F-4(7/2)+I-4(13/2)) states.
