Abstract

The thin structure of KDP crystals was studied using multicrystal x-ray diffraction analysis of high resolution and two-crystal topography for reflection. KDP crystals grown from aqueous solutions are characterized by the impurity striated structure caused by the fluctuation of the growth processes, the latter results in the nonuniform penetration and distribution of impurities and formation of low angle turns during a layer-by-layer growth. Low angle quasi-boundaries separating the strips of the normal growth are perhaps of a nondislocational origin. A qualitative correlation between the concentration of low angle quasi- boundaries in the crystal and the value of bulk laser damage threshold has been found.
