Abstract
Using IR absorption spectroscopy in the stretching region of OH groups and Raman spectroscopy in the region of two-particle states of acoustic phonons, we have demonstrated that high-temperature top-seeded solution growth from a melt of congruent composition containing 6.0 wt % K2O flux in Kristall-2 commercially available growth units makes it possible to obtain nearly stoichiometric LiNbO3 crystals having approximately the same perfection of the proton sublattice as in stoichiometric crystals grown from a melt containing 58.6 mol % Li2O, but considerably surpassing them in general optical and structural homogeneity.
