L-Histidine Barium Chloride dihydrate (LHBC), a semi organic nonlinear optical material was grown from aqueous solution by slow solvent evaporation method at room temperature.  The LHBC crystals were characterized by X-ray powder diffraction analysis.  The presence of functional groups was identified through Fourier Transform Infrared Spectroscopy.  Thermogravimetric and Differential Thermal Analysis confirm that the crystal is stable up to 269oC.  The mechanical properties of the grown crystals have been studied using Vickers microhardness test.  The second harmonic generation behavior of LHBC crystal was tested by Kurtz-Perry powder technique.
