The synthesis of pure L-asparagine and its based crystal such as L-asparagine admixture with potassium bromide using de-ionized water as solvent (LAPB)was carried out by taking L-asparagine and potassium bromide in the molar ratio 2:1.The solubility of the grown crystals were carried out by gravimetrical method. Using the powder X-ray diffraction study the crystalline of pure L-asparagine and LAPB crystals were confirmed. The various functional groups of the grown crystals were assigned from FTIR study. The optical transmittance range obtained from UV-visible transmittance. The second harmonic generation (SHG) test confirms the NLO property of the grown crystals by kurtz and Perry and it was compared with KDP. The microhardness measurements were estimated by Vickers hardness test.
