ABSTRACT:
A number of publications containing structural data, characteristics of nonlinear optical properties of pure and doped crystals of
potassium titanyl phosphate (KTP) family have been reviewed to analyze the
structural and symmetry conditionality of nonlinear optical properties of these
crystals. The pseudosymmetric features of KTP-type crystals with respect to
inversion are investigated. Specifically, pseudoinversion distribution maps are
calculated; pseudoinversion extrema and coordinates of pseudoinversion centres
are found; and the distributions of pure and doped KTP-type structures and
their individual atomic sublattices over the degree of pseudoinversion are
analyzed. A correlation between the characteristics of nonlinear optical
properties of a number of crystals belonging to the KTP family and the degree
of pseudoinversion of their atomic structures is demonstrated.
