Single crystals like lithium niobate are frequently doped with optically active rare earth or transition metal ions for a variety of applications in optical devices such as solid state lasers, amplifiers or sensors. From a practical point of view it would be very attractive to create a material system where the energy of the emitted photons is close to the pumping energy, therefore the intention in integrated optics was to explore the IR region and more specifically the three telecommunication windows laying between 0.9 and 1.6 µm. To exploit the potential of the Er: LiNbO3 one must ensure high intensity of the 1.5 µm luminescence as an inevitable prerequisity. For that generally crystalline materials are particularly suitable, due to that well known fact that crystal field formed by the atoms surrounding the lasing ions can strongly affect the resulting luminescence properties. The ion implantation technique is one of the ways to prepare a laser active ions doped optical layers.
