Abstract: The search for new advanced materials is an important area of contemporary research in numerous disciplines of science and development of many new technologies. Nonlinear optical (NLO) crystals have been a great deal of interest in recent years due to their potential applications in the domain of optoelectronics and photonic technologies. The thesis consists of nine chapters discussing important and interesting issues in relation to growth and characterization of NLO crystals. A brief introduction to various growth methods with emphasis on low temperature solution growth and an overview on NLO crystals with their characteristics has been presented in detail. The single crystal growth of organic bis(2-aminopyridinium) maleate (B2AM) by low temperature solution growth method and their characterization analysis are discussed. Crystalline perfection of the as grown single crystal was studied through high-resolution X-ray diffraction (HRXRD) analysis. Dielectric measurements indicate that B2AM crystal has low values of dielectric constant and dielectric loss. The cutoff wavelength of B2AM at 354 nm is revealed by the optical transmission studies. Presence of various functional groups was identified by FTIR spectrum analysis.The studies on semiorganic NLO single crystals of tris(glycine) calcium(II) dichloride (TGCC) is presented. HRXRD analysis shows that crystalline perfection of TGCC crystals is quite good. Thermal studies of TGCC were determined. The SHG relative efficiency of TGCC is 1.5 times that of KDP. The reverse indentation size effect on the (001) plane of TGCC crystal was identified by mechanical studies.The growth of potassium carbonate doped KDP crystals in different molar ratios is discussed. It was observed that measured SHG efficiency and piezoelectric coefficient of doped ADP crystals are higher than that of pure ADP crystal. The summary of the present investigations and suggestions for future research activities are presented. newline
