Growth and Characterization of Sulphamic Acid Lithium Chloride Single Crystal

Indumathi, Deepa, Madhavan, Senthil
The third order nonlinear optical single crystal of Sulphamic Acid Lithium Chloride (SALC) was grown by slow evaporation method at room temperature. The grown single crystal was characterized by single crystal X-ray Diffraction (XRD) analysis; it confirms the crystal belongs to the orthorhombic system. The vibrational mode of SALC was identified by Fourier Transform Infrared (FTIR) spectral analysis. UV-Vis-NIR absorption studies were performed to know the optical behaviour of the SALC single

Further the Third order nonlinearities of the SALC crystal was studied by Z-scan techniques. The values of non-linear refractive index (n 2), absorption coefficient (β), and third order non-linear susceptibility (χ 3) were found.
