Abstract

Growth of a desirable quality single crystals of L-glutamic doped potassium dihydrogen phosphate (KDP) a semi-organic nonlinear optical (NLO) material is reported. The crystals of dimensions 7 x 3 x 1 mmЗ were obtained from its aqueous solution by slow solvent evaporation technique. The harvested crystals have been characterized by XRD, dielectric and ferroelectric properties. The increase in the value of ferroelectric charge coefficient has been found 0.6 pc/N on polling the sample at 1 kV/cm, which confirm its use for a nonlinear optical material..
