Growth of low-scattering single-domain photorefractive LiNbO/sub 3/ crystals

Abstract:

Low-scattering single-domain LiNbO/sub 3/ crystals can be grown from a 3 mol% LiVO/sub 3/-doped LiNbO/sub 3/ (50 mol% Li/sub 2/O-50 mol% Nb/sub 2/O/sub 5/) quasi-flux system. Approximately one order of magnitude less scattered light was detected in this crystal than in the commercially available congruent reference LiNbO/sub 3/ 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 LiNbO/sub 3/ single crystals. These crystals may be promising for high-density holographic data storage applications.
