Crystal Growth and Characterization of a Novel Non Linear Optical Single Crystal of Urea Phthalic Acid

The Nonlinear optical (NLO) material of Urea Phthalic acid (UPA) was grown by slow evaporation method. The unit cell parameters were determined by single crystal XRD. The fundamental frequency vibrations of UPA were identified by FTIR analysis. The optical properties of UPA were determined by UV-Vis spectral studies. The Laser damage threshold value of UPA single crystal was found to be 5.3 GW/Cm². Z-scan techniques with He–Ne laser has measured the optical nonlinearity of UPA crystal. (paper)
