Abstract
The luminescence quantum efficiency of different laser transitions in rare- earth-doped lithium niobate is determined from photoacoustic and luminescen ce excitation signals. High quantum efficiencies have been obtained for the transitions relevant for optical applications of the different ions (Nd3+, Er3+, Tm3+ and Yb3+). Evidence of site dependent quantum efficiency and up -conversion effects are also demonstrated in Yb3+/Mg2+ and Er3+/Yb3+ co-dop ed crystals. (C) 2000 Elsevier Science B.V. All rights reserved.
