In the present investigation, single crystals of L-Aspartate were grown successfully by slow cooling method. Powder X-ray diffraction(XRD) studies were carried out for the grown crystal and the lattice parameters were calculated. Absorption of the grown crystal was analysed using UV-VIS -NIR studies and it was found that these crystals possess minimum absorption from 360 nm to 2250 nm. The crystal was characterized by FTIR and Thermal studies. Nonlinear optical property of the grown crystal was also studied by Kurtz-Perry powder technique.
