ABSTRACT: The influence of mixed acids in the growth and characteristic properties of a nonlinear optical
material L-glutamic acid hydro chloro bromide abbreviated as LGAHCB was examined. Single
crystal X-ray diffraction analysis was used to calculate the lattice parameters of the crystals.
Fourier transform infrared spectroscopies were performed to study the molecular vibrations of
the grown crystal. The optical transmission spectrum shows very low absorption in the entire
visible region. The powder second harmonic generation efficiency of LGAHCB is 1.5 times
efficient as potassium dihydrogen phosphate (KDP).
