Na2O-doped (up to 3 mol% Na in the melt) LiNbO3 crystals have been grown by the Czochraski method. The experimental results show that Na2O dopants can increase the ability of LiNbO3 to resist light-induced optical damage, but the photorefraction of L

The accurate refractive indices in visible range and their Sellmeier equations have been obtained for a series of LiNbO3: Mg (5 mol%) crystals with Ti or Nd doping. The phase matching angle for 1.064μm calculated by Sellmeier equation gives good agr

The absorption spectra, photoconductivities and photovoltaic currents of LiNbO3:Fe crystals with different Mg doping levels and Li/Nb ratios in the oxidized state have been investigated at room temperature. The Fe2+ ions in LiNbO3:Mg:Fe with Mg conte

The X-band electron paramagnetic resonance of eight LiNbO 3 : Fe crystals with different Mg doping levels and Li Nb ratios was studied at room temperature. The EPR spectra obtained fall into two classes with quite different spin-Hamiltonian parameter

The influence of Nd:MgO:LiNbO3 composition on the optical quality and resistance to photorefraction has been studied. Nd:MgO:LiNbO3 (1 mol% Nd2 O3, 7.5 mol% MgO) crystal has been found to have enhanced resitance to photore- fraction, lower phase matc

With relation to photorefraction, it has been found that higher light irradiation intensities can be withstood by Li-rich LiNbO3:Mg (5 mol%) than by the congruent LiNbO3:Mg (5 mol%). The photoconductivity of the former is an order of magnitude larger

The ability of Li-rich LiNbO3:Mg(5mol%):Fe(0.1wt%) to resist photorefraction is found to be comparable to that of LiNbO3:Mg (5mol%), even though the photorefraction sensitive dopant Fe is added. The nuclear quadrupole splitting and isomer shift of 57

The space chages formed in the process of photorefraction in LiNbO3 crystals is visualised by charged powder techniques. The results confirmed the existence of space charge carriers at the periphery of the illuminated region with negative charge carr
