Organic proton transferred nonlinear crystal of Creatininium p-Toluenesulfonate (CPT) has crystallized in with the help of typical solvent evaporation method. The crystal system of grown CPT crystal is orthorhombic with noncentrosymmetric space group P212121 and its crystalline perfection of grown CPT crystals was identified by HRXRD. Functional groups of the grown CPT crystal were identified by FTIR. The optical transmittance of grown CPT crystal starts from the lower visible region to IR region. The surface damage of grown CPT crystal induced by laser was studied and their threshold value was calculated. The emission region of the grown CPT crystals is in yellow wavelength region. The mechanical strength of CPT crystals resides to soft material category. The Second order nonlinearity was studied and compared with standard KDP. The Differential scanning calorimetric (DSC) confirms grown CPT crystal is thermally stable upto 190 ºC and the result confirm that the crystal has good thermal stability and it is suggested for electro-optical applications.
