“…1 NLO materials in their single crystal form have wide applications in high-energy lasers for inertial confinement fusion research, 2 color display, electro-optic switches, frequency conversion, etc. 3 Hence, there is a great demand to synthesize new NLO materials and grow their single crystals. Most of the anisotropic physical, optical, and electrical properties of the single crystals get deteriorated or completely diminished when these are not in the single domain crystal or having the defects like structural grain boundaries.…”

Effect of L-threonine ͑LT͒ doping on crystalline perfection, second harmonic generation ͑SHG͒ efficiency, optical transparency, and laser damage threshold ͑LDT͒ in potassium dihydrogen phosphate ͑KDP͒ crystals grown by slow evaporation solution technique ͑SEST͒ has been investigated. The influence of doping on growth rate and morphology of the grown crystals has also been studied. Powder x-ray diffraction data confirms the crystal structure of KDP and shows a systematic variation in intensity of diffraction peaks in correlation with morphology due to varying LT concentration. No extra phase formation was observed which is further confirmed by Fourier transform Raman ͑FT-Raman͒ studies. High-resolution x-ray diffraction curves indicate that crystalline perfection has been improved to a great extent at low concentrations with a maximum perfection at 1 mol % doping. At higher concentrations ͑5 to 10 mol %͒, it is slightly reduced due to excess incorporation of dopants at the interstitial sites of the crystalline matrix. LDT has been increased considerably with increase in doping concentration, whereas SHG efficiency was found to be maximum at 1 mol % in correlation with crystalline. The optical transparency for doped crystals has been increased as compared to that of pure KDP with a maximum value at 1 mol % doping.

“…In general, most of the organic molecules designed for nonlinear optical (NLO) applications are the derivatives of an aromatic system substituted with donor and acceptor substituents [1][2][3]. On the search of new NLO materials with better mechanical properties, many researchers have focused on the small organic molecules having a large dipole moment and a chiral structure.…”

“…In recent years, organic materials have attracted many researchers due to its high nonlinearities, ultrafast response in electrooptic effect, large optical susceptibilities, large second order molecular polarizability, and higher resistance to optical damage and they have wide applications in optical communications, frequency mixing, optical parametric oscillation, information storage, and so forth [1][2][3][4]. According to crystal engineering, second harmonic generation occurs mostly in noncentrosymmetric crystals due to nonzero hyperpolarizability.…”

A new organic charge transfer molecular complex salt of benzimidazolium salicylate (BSL) single crystals was grown by the slow evaporation solution growth technique using methanol as a solvent at room temperature. The grown crystals were characterised by single crystal X-ray diffraction (XRD) which confirms that the crystal belongs to monoclinic system with the centrosymmetric space group P2 1 / . The crystalline perfection of the grown crystal was analyzed by high resolution X-ray diffraction (HRXRD). The presence of various functional groups was identified by FTIR spectrum. UV-Vis spectral study reveals that the BSL crystal is optically transparent in the wavelength region 342 nm-1100 nm. Dielectric measurements of the crystal at various frequencies were also determined. The mechanical properties of the grown crystal were assessed using Vickers microhardness testing. Nonlinear optical property of the crystal was confirmed using Kurtz and Perry powder technique and the SHG efficiency of the BSL crystal is 0.7 times greater than that of the standard KDP crystal.
