This paper presents the growth of optically non-linear organic crystal Glutamic acid using water by slow evaporation of aqueous solution at room temperature. The compound crystallizes in non-centrosymmetric space group P21/C. The FT-IR spectrum was recorded using a Perkin-Elmer FT-IR spectrometer. The optical characterization of the crystal shows the cut off wavelength near the UV region and also the bandgap for crystal were calculated. The mechanical response of the crystal has been studied using Vickers microhardness technique. The elastic stiffness constant (C11) were calculated for different loads using Wooster’s empirical formula. Static and dynamic hyperpolorizability values were calculated to confirm the suitability of the crystal for nonlinear applications.
