Electronic, nonlinear optical and optical limiting properties of 2-amino-3-propanoic 4-methylbenzenesulfonate (2A3PMS) single crystal

An organic 2-amino 3-propanoic 4- methylbenzenesulfonate (2A3PMS) crystal with dimensions 27x4x3 mm was grown using water as solvent by adopting slow evaporation solution growth technique. The lattice parameters and space group of the crystalline compound was confirmed using single crystal X-ray diffraction study. The grown crystal (2A3PMS) crystallizes in the orthorhombic system with non-centrosymmetric space group, P222. Dielectric properties such as dielectric constant and dielectric loss were studied as a function of temperature and frequency to find the charge distribution within the crystal. The nonlinear absorption coefficient, nonlinear refractive index and nonlinear optical susceptibility of the grown crystal were determined using Z-scan technique. The optical limiting behavior of the 2A3PMS crystal is found to saturate with threshold and amplitude of 18.091 mW and 4.70 mW respectively.
