Growth and Study of OH Absorption Band in Doped LiNbO3 Crystals
R.K. Choubey, P.K. Barhai, S. Kar, P. Sen and K.S. Bartwal

Undoped, Mg doped and Mg, Nd codoped LiNbO3 crystals were grown by conventional Czochralski technique. Comparative study was carried out using Fourier transform infrared (FTIR) spectroscopy. Infrared optical absorption for OH ion has been used to study the effect of impurities on the crystals. The OH absorption band shifted from its original position i.e. 3484 cm1 and some new band arises.

Keywords: Optical materials, czochralski technique, infrared spectroscopy.
