Results of theoretical studies are presented of linear and nonlinear optical properties of some metal tartrate crystals
using DFT FP-LAPW ab-initio calculations. The dispersion dependence of the complex dielectric permittivity in
WIEN2k package and the second order nonlinear susceptibility in ABINIT package have been calculated. The calculated
second-order nonlinear susceptibilities at 1.064 ?m are compared with those obtained earlier in the experiment.
Calculated spectra of optical properties of strontium, manganese, copper, ammonium and calcium tartrate crystals
have been obtained for the first time.
