Growth of Sodium acid phthalate (NaAP) single crystals for harmonic generation applications
Good quality optical single crystals of Sodium acid Phthalate (NaAP) single crystal were grown by different techniques such as solvent evaporation, slow cooling and seed rotation techniques. Transparent and optically good quality single crystals were obtained from, seed rotation technique. X ray diffraction analysis confirms that the crystal belongs to orthorhombic system with a space group of B2ab. Spectroscopic analysis were carried out confirm the presence of functional groups present in the compound. Linear and non linear optical properties of the grown crystals were confirmed through spectroscopic and through harmonic generation measurements. These preliminary investigations confirm that the present sodium acid phthalate crystals can be a potential candidate for nonlinear optical applications. The results are discussed in detail.
