Investigations on the physicochemical properties of the nonlinear optical crystal for blue green laser generation

Bisglycinehydrogenchloride (BGHC) an intriguing material for frequency conversion has been grown by slow evaporation solution growth technique at room temperature. Their structural, optical and physicochemical properties were characterized by X-ray powder diffraction, FTIR. Raman and UV-vis spectra. The title crystal has found to crystallize into noncentrosymmetric orthorhombic P2(1)2(1)2(1) space group. The material has a wide transparency in the entire visible region. It is found that the cutoff wavelength lies in the UV region. The mechanical response of the crystal has been studied using Vickers microhardness technique. The Kurtz powder second harmonic generation test shows that the compound is a prospective crystalline material for second order nonlinear optical application. (C) 2007 Elsevier B.V.
