Non-linear optical properties of α-glycine single crystals by Z-Scan technique


Single crystals of α-Glycine up to the size of 4 x 4x1 mm3 were grown for optical characterization by the solution growth method using methanol as a solvent. The crystal structure was studied by X-ray diffraction. The UV–visual absorption spectra indicate a good transparency between 200 and 1400 nm. The non-linear refractive index n2 and susceptibility χ (3) have been measured through the Z-scan technique. α-Glycine exhibits saturation absorption and self-focusing performance. Non-linear absorption co-efficient β is determined as 2.4763 x 10 – 5 cm/W. Non-linear refractive index n2 measured at the wavelength of 632.8 nm is calculated as 2.14435 x 10-8 cm2 /W. The real and imaginary pars of χ(3) have been measured at 632.8 nm and found to be 7.9732 x 10-07 esu and 8.0018 x 10-07 esu, respectively. The measured 3rd order non-linear properties confirm its suitability for non-linear optical devices such as optical switching device.
