Lauric acid crystals were grown with potassium bromide (LAPB) in aqueous solution at room temperature by slow solvent evaporation technique. The monoclinic structure of grown single crystal was studied by single-crystal X-ray diffraction and powder X-ray diffraction analyses. The Fourier transform infrared spectrum incorporates signatures of functional groups. The optical absorbance study reveals the UV cutoff wavelength as 230 nm. The Kurtz powder technique ensures that LAPB crystal has 1.1 times greater second harmonic generation efficiency than that of KDP crystals. The thermogravimetric and differential thermal analyses ensure that the material has good thermal stability. A dielectric behaviour of the sample material is studied in the frequency range 10 1-10 6 Hz.

“…Recently, the nonlinear optical materials with enhanced third order nonlinear optical susceptibility χ 3 have been used in wide range of applications such as 3D optical memory, optical switching, optical modulating, laser technology, optical communication, optical storage technology and optical limiting etc,. In the few decades, many organic and inorganic materials have been developed to cover the possible applications in Ultraviolet (UV), near and far-infrared (IR) wavelength regions [1, 2, 3, 4, 5, 6, 7, 8]. Inorganic crystals have high laser-induced damage threshold energy compared to organic crystals, the materials with high nonlinear absorption, ultra fast response time and large third order optical nonlinearity are essential in two photon laser scanning microscopy, phase conjugation, low intensity lasers and microfabrication [9].…”

Single crystals of pure and NaCl doped sulphamic acid (SA) were grown by slow evaporation method at room temperature. The lattice parameters and structure were determined by using single crystal and powder X-ray diffraction analyses. The presence of dopant in the SA lattice was affirmed by EDAX analysis. UV-Vis spectra show maximum transmittance in the visible region. The band gap energies were found to be 6.06 eV and 5.70 eV for pure and NaCl doped SA crystals respectively. From the PL specta the emission were observed at 335 and 424 nm for pure and 340 and 428 nm for doped SA crystal. The thermal stability of the grown crystals were analyzed by thermogravimetric and differential thermal analysis (TGA/DTA) and revealed that the grown crystals were thermally stable up to 331 °C and 334 °C for pure and NaCl doped SA. Vickers microhardness study reveals that the hardness of the crystals is increase with increasing load. The photoconductivity study shows that the grown crystals are negative photoconductive nature. The Laser Damage Threshold (LDT) indicates the grown crystals have good resistance to laser radiation than a standard Potassium dihydrogen phosphate (KDP) crystal. The Z-scan technique was employed to determine the nonlinear refractive index, nonlinear optical absorption and third order nonlinear optical (TONLO) susceptibility of the grown crystals using He–Ne laser.
