摘要: Abstract Codoping RbTiOPO 4 crystals (RTP) with Er 3+ and Nb 5+ is interesting in order to merge the rare earth ion photoluminescence non-linear optical properties of matrix, favouring self-induced effects. Using RTP doped , a concentration similar that obtained other laser matrices was achieved. In this work, structure RbTi 0.927 0.056 0.017 OPO has been thoroughly studied by high-resolution neutron diffraction. Particular attention paid positions occupied distortion their respective coordination polyhedra. Finally, second-harmonic generation efficiency sample determined compared members family.
