Abstract

Potassium dihydrogen phosphate (KDP) is a well known nonlinear optical (NLO) material having different applications in electro-optics and laser technology. Pure and amino acid L-arginine doped KDP single crystals were grown by the slow solvent evaporation technique. The 0.3, 0.4 and 0.5 weight % doping of L-arginine was successfully achieved in KDP crystals and confirmed by paper chromatography, CHN analysis, FTIR and UV-Vis spectroscopies. The dielectric behaviour of the samples has been studied. The variation of dielectric constant, dielectric loss (tanδ), a.c. resistivity and a.c. conductivity with frequency of applied field in the range from 100 Hz to 100 kHz is reported. The effect of amino acid doping was observed on SHG efficiency. The results are discussed.
