An organic electro-optic and nonlinear optical (NLO) material, L-alaninium oxalate, was synthesized by the standard method. The synthesized material was purified by repeated recrystallization. Single crystals were grown by the slow evaporation technique. The grown crystals were transparent and had optimum dimensions (20 x 3 x 2 mm³) and were characterized by single crystal XRD, FT-NMR, FT-IR, TGA-DTA and UV-Vis-NIR techniques. The second harmonic generation (SHG) from the material was confirmed using Nd:YAG laser.
