Good quality L-tartaric acid (LTA) single crystal of size 10mm × 3mm × 2 mm has been grown by slow solvent evaporation technique. Single crystal X-ray diffraction analysis reveals that the crystal belongs to the triclinic crystal system with space group . Using FT-IR, spectral analyses were identified. UV–Visible optical analysis has been performed to, determine the optical transparency of LTA crystal in the range of 200–1200 nm, and the optical band gap was calculated using Tauc’s plot, and the value was found to be 5.1eV. Laser damage threshold studies were carried out to the grown crystals. A powdered sample of LTA was tested by second harmonic generation.
