Studies on the growth, structural, optical and laser damage threshold properties of 4-aminopyridinium p-aminobenzenesulfonate p-ammoniobenzenesulfonate monohydrate crystal

An organic nonlinear optical crystal 4-aminopyridinium 4-aminobenzenesulfonate 4-ammoniobenzenesulfonate monohydrate (4APABS) was grown by slow evaporation solution growth technique. The cell parameters of grown crystal were confirmed by single crystal X-ray diffraction analysis. High resolution X-ray diffraction studies revealed the crystalline perfection of grown crystal. The functional groups present in title compound were confirmed by FTIR spectral studies. UV–vis spectral studies revealed that the grown crystal is transparent in the entire visible region. Single and multiple shots laser induced surface damage threshold values of the grown crystal were measured using Nd:YAG laser. The relative second harmonic generation efficiency of grown crystal was found to be 2.2 times that of KDP crystal.
