## Abstract The method of studying the dimensional distribution of the density of dislocations revealed the effect of different stages of process of growth upon the structural perfection of crystals of LiNbO~3~, grown by the Czochralski's method. Probable reasons for development of dislocations are

## Abstract An information is given on the kinetics of developing ionization defects by Ξ³βradiation, as well as on the destroying of these defects as a result of thermal treatment in oxidizing atmosphere at different temperatures. The presence of several types of ionization defects developing by Ξ³β
Raman spectra of a series of MgO-doped congruent LiNbO, crystals were obtained with MgO concentrations up to 30 mole%. Single crystals were successfully grown and no precipitates were discovered. The intensity, frequency and line width of the Raman phonons were studied as a function of doping percen
