N2 - In this study the laser-heated pedestal growth (LHPG) method was used to grow lithium niobate (LiNbO3) single crystal fibers with different compositions ratios [Li2CO3MNb2O5] = 44:56, 45:55, 46:54, 47:53, 48:52, 48.3:51.4, 49:51 and 50:50 achieved by different seed rods. X-ray Single-Crystal Diffractometer (X-Ray/CCD) was used to determine the lattice parameters and crystalline structure of the crystals. The UV absorption spectrum, Fourier-transform infrared spectrometer and Raman scattering spectroscopy results were used to find the optical properties and standard characterization of the different LiNbO3 single crystals. We note that the wavelength of the UV absorption edge and the wave number of the O-H absorption peak were less when the Li2O composition was large. The plotted results tended to fit a Gaussian curve. The Full-Width Half-Maximum (FWHM) of the Raman peak found at 152 cm of the E(TO) mode decreased linearly as the amount of the Li2O composition increased. The Raman scattering results showed that the structure at the UNbO3 crystal became more rigid when the amount of the Li2O composition increased.
