摘要：

L-Lysine doped Oxalic acid single crystals were grown by conventional slow evaporation solution growth technique. The unit cell dimensions were estimated by single crystal x-ray diffraction analysis. Spectral properties and functional groups of the title material were identified by FTIR spectral analysis. Linear optical characteristics of the material were examined by UV-Vis-NIR spectral analysis. The mechanical stability was assessed by Vicker's hardness and it was observed that the load varies linearly with hardness value. Through NLO analysis the title material was found to be a phase matchable crystal. Third order nonlinear optical susceptibility of the material was tested by Z-scan technique and it was found to be in the order of 10(-6) esu. Optical limiting action of the sample at 532 nm was demonstrated using CW laser beam since the title material possesses self-defocussing effect. (C) 2018 Elsevier Ltd. All rights reserved.
