Abstract
Conditions for the growth of LiNbO3:MgO single crystals by the Czochralski method were optimized. An upper limit of the molar MgO concentration in the melt for obtaining limpid, optically homogeneous crystals was determined. The Curie temperature was measured on precisely defined samples and so real MgO contents in the single crystal phase, distribution coefficients and longitudinal concentration profiles could be determined using this calibration curve. X-ray diffraction and optical absorption in the near infra-red and in the ultra-violet and visible regions were also studied on LiNbO3:MgO single crystals. Lattice constants and positions of the OH− absorption band and of the short-wave absorption edge were determined on the basis of described measurements. Dependences of all the above-mentioned properties on the molar MgO concentration were found out. The simple model of microscopic mechanisms for explaining these experimental data was proposed.
