In the present scenario, nonlinear optical single crystals are very much useful in the field of second harmonic generation, fibre optic communication, electro-optic modulation, etc. In order to satisfy the above said requirements, crystal researchers have to find out novel and efficient nonlinear optical materials. In the recent past semi-organic materials are more attractive because of its dual characteristics of organic and inorganic systems. In the present communication, we have successfully synthesized the semi-organic nonlinear optical material of l-histidine bromide (LHB) and the single crystal has been grown by slow evaporation solution growth technique. The formation of the synthesized compound was confirmed by Fourier transform infrared (FTIR) analysis and the lattice dimensions have been determined from the powder X-ray diffraction analysis. Its crystalline perfection was examined by high-resolution X-ray diffractometer (HRXRD) and found to be an excellent. Its refractive index and birefringence have been studied. Its optical and electrical properties have been assessed by UV–vis, photoluminescence and dielectric measurements, respectively. Its laser damage threshold was determined by adopting Nd:YAG laser as a source.
