Abstract Organic single crystal of p-Toluidinium L-Tartrate (PTLT) was grown from aqueous solution by slow evaporation technique. X-ray diffraction analysis confirmed the crystal structure and high resolution XRD showed the crystalline perfection of the grown crystal. UV-visible spectral analysis revealed the cut-off wavelength at deep UV region and band gap energy of the grown crystal. The second order nonlinear optical properties of the grown crystal were ascertained by Kurtz-Perry powder technique. The laser damage threshold value of PTLT (2.0 GW/cm 2 ) was estimated and it is relatively higher than that of Ammonium hydrogen L-Tartrate single crystal (0.53 GW/cm 2 ). The optical studies demonstrated that the PTLT crystal could be a potential organic NLO material for frequency doubling applications.
