ORGANIC NONLINEAR-OPTICAL CRYSTALS OF BENZOYL GLYCINE

The single crystals of organic nonlinear optical material, benzoyl gly cine were grown by the solvent evaporation technique using N,N-dimethy l formamide as solvent. Single crystals of size 20 x 10 x 5 mm(3) were obtained. The UV-VIS spectrum shows a cut-off wavelength less than 30 0 nm. The grown crystals were characterized by X-ray powder diffractio n, IR, NMR and mass spectroscopy. The second-harmonic generation effic iency in these crystals is found to be 1.5 times higher than that in K DP. (C) 1998 Elsevier Science B.V. All rights reserved.
