Abstract :
Low-scattering single-domain LiNbO3 crystals can be grown from a 3 mol% LiVO3-doped LiNbO3 (50 mol% Li 2O-50 mol% Nb2O5) quasi-flux system. Approximately one order of magnitude less scattered light was detected in this crystal than in the commercially available congruent reference LiNbO3 sample. For quantitative scattering measurements an integrating sphere technique developed at Lasergenics Corp. was utilized. Although no direct evidence can prove the improvement of the Li-Nb-O stoichiometry, the “as grown” single-domain character, the higher refractive index, and the significantly lower scattering are indirect evidences revealing unusual changes and improvements in the quality of the LiNbO3 single crystals. These crystals may be promising for high-density holographic data storage applications
