We have focused on the structure of Er:LiNbO3 layers created by 330 keV erbium ion implantation (fluences 1,0x1015, 2,5x1015and 1,0x1016 cm-2) in the X, Z and two various Y crystallographic cuts of LiNbO3. Five hours annealing at 350°C was applied to recrystallize the as-implanted layer and to avoid clustering of Er. Depth distribution of implanted Er has been measured by Rutherford Backscattering Spectroscopy (RBS) using 2 MeV He+ ions. Defects distribution and structural changes have been described using the RBS/channelling method. Data obtained made it possible to reveal the relations between the crystallographic orientation of the implanted crystal and the behaviour during the restoration process. The deepest modified layer has been observed in the perpendicular Y cut, which also exhibits the lowest reconstruction after annealing.
