Abstract
Optically transparent single crystal of Bis-glycine hydrobromide (GHBr) is developed by cost effective slow solvent evaporation method. The GHBr crystal is tested with X-ray diffraction study to understand the molecular structure. Present material crystallizes in the orthorhombic system with the space group of P2(1)2(1)2(1). Spectro-scopic studies like FTIR and FT-Raman are carried out on the crystal to confirm the functional groups and to understand the presence of metal vibrations. Chemical construction of the material is further confirmed by H-1 NMR and C-13 NMR studies. The optical transmittance and optical band gap energy of the crystal are observed to be 75% and 5.53 eV respectively. The third order optical nonlinearity analysis are carried out on the crystal using Z-scan setup and the nonlinear optical susceptibility (chi(3)) and refractive index (n(2)) values are estimated to be 1.28 x 10(-6) esu and -0.96 x 10(-8) cm(2)/W respectively. The grown crystal is subjected to single shot laser damage threshold (LDT) study and its value is calculated to be 2.54 GW/cm(2).
