Nonlinear optics is a fascinating field, which plays a vital role in the emerging field of photonics and optoelectronics. A nonlinear optical crystal of L-alanine grown in aqueous solution of hydrofluoric acid is done by slow evaporation method. L-alanine is an NLO material and it has a Second Harmonic Generation (SHG) efficiency of about 0.3 times that of KDP. To alter the various properties of L-alanine, single crystals of L-alanine have been grown in the aqueous solution of hydrofluoric acid. In this work, L-alanine was admixtured with hydrofluoric acid (LAHF) in the molar ratio of 1:1. The grown crystals were colorless and transparent and they were subjected to various studies for characterization.The third-order nonlinearities of LAHF crystal have been investigated by Z-scan method. The values of nonlinear refractive index (n2), the nonlinear absorption coefficient (ß) and third-order nonlinear susceptibility (?(3)) are estimated for the sample
