| Abstract: | A new organic nonlinear optical (NLO) material, L-asparaginium Oxalate (ASOX) was synthesized and single crystals of ASOX with dimension (10*5*5) mm3 was grown from aqueous solution by slow evaporation solution growth technique. Single crystal XRD data reveals that ASOX belongs to triclinic crystallographic system with non-centrosymmetric space group P1. The grown organic NLO crystal was subjected to various characterizations like PXRD, FT-IR analysis, thermal studies, micro hardness test and optical studies for identifying the transparency range and the emission spectrum. The laser damage threshold value was found to be 2.04 GW/cm2. The second harmonic efficiency of the grown crystal was examined using Kurtz Perry powder technique and it was found to be 68% that of KDP. Hence it can be effectively employed for various optoelectronic and photonic applications. |
