Single crystal of Thiourea Sodium Sulphate (TSS) was prepared by a slow evaporation technique. The optical absorption and absorption coefficient are studied by UV. Vis.-NIR The voids or defects of the TSS crystal were carried out by its surface morphology analysis by SEM. The NLO properties of shocked TSS single crystal were estimated by UV-Vis-NIR spectroscopic analysis. Finally the nonlinear optical property of TSS crystal was estimated by Second Harmonic Generation (SHG) and the suitability of present titled mono crystal against mechanical resistivity after the shock for non linear optics and for photonic application has been confirmed.

L-asparagine L-tartrate (LAT), an organic compound has been synthesized from aqueous solution and bulk single crystal has been grown by slow evaporation technique. Powder X-ray diffraction studies confirmed the monoclinic structure of the grown LAT crystal. The presence of functional groups of the grown crystal was identified by FTIR studies. Linear optical property of the grown crystal was studied by UV-Vis spectral analysis. Microhardness studies reveal that the crystal possesses relatively higher hardness compared to other organic nonlinear optical crystals. Dielectric response of the L-asparagine L-tartrate crystal was analyzed for different frequencies at various temperatures. Kurtz-Perry powder second harmonic generation test confirmed the nonlinear optical properties of the as-grown LAT crystal.

Semiorganic optically transparent Bis(4-nitrobenzoate) tetraaquamanganese (II) dihydrate [Mn (p-NO2C6H4COO)2 (H2O)4]·2H2O (BNMD) single crystals were grown by slow evaporation technique at room temperature. Single crystal X-ray diffraction analysis was carried out to determine the lattice parameters of the crystal. Powder X-ray diffraction pattern was recorded and indexed for the structural confirmation. The crystalline quality was confirmed by HRXRD. The presence of functional group in the compound has been confirmed by FTIR analysis. UV-Visible transmission spectrum has been recorded to determine the cut-off wavelength region of the crystal. The Second Harmonic Generation of BNMD crystal was confirmed by Kurtz-Perry powder method using Nd:YAG laser and found to be 0.59 times that of KDP. The dielectric response of the crystal was also investigated and reported. The microhardness study reveals that the hardness number (Hv) increases with load. From the values of work hardening coefficients, it was concluded that BNMD crystal belong to the category of soft materials. Thermal studies were performed using differential thermal analysis (DTA).
