However, only doping of the samples during growth is available up to now, which yields a quite homogeneous doping density. In the present work, we deposit Er$^{3+}$-ions by the focused ion beam technique at Yttrium sites with several fluences in one sample. With a photoluminescence study of these locally doped Er$^{3+}$:Y$_2$SiO$_5$ crystals, we are able to evaluate the efficiency of the implantation process and develop it for the highest efficiency possible.
