A new semi organic nonlinear optic material L-Histidine Sodium Sulphate anhydrous (LHSS) was synthesized. The grown crystals were characterized by single crystal X-ray diffraction analysis to determine the cell parameters and by FTIR technique to study the presence of the functional groups. Thermogravimetric and differential thermal analysis reveals the thermal stability of the crystal. UV-VIS-NIR spectrum shows excellent transmission in the region 200-1100 nm. Mechanical properties of the grown crystal were studied using Vicker’s micro hardness test. Second harmonic generation efficiency of the powdered LHSS was tested using Nd:YAG laser and it is found to be 0.3 times of KDP crystal.
