Abstract :

A Nonlinear Optical (NLO) material has a nonlinear response to the electric field associated with the light of a laser beam, leading to a variety of optical phenomena such as generation of new light frequencies. 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 and 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
