The Er 3+ doped Mg:LiNbO 3 single crystal fibers employed in our experiment were grown in air by a micro‐pulling down (μ‐PD) method from host materials of a congruent Li/Nb (0.945) ratio which were melt‐doped with a nominal molar concentration of 1, 3, 5% MgO and 0.6% Er 2 O 3 . The X‐ray diffraction analysis results indicated that the co‐doped crystals main tained the same structural characteristics as the undoped LiNbO 3 , however the lattice parameters with Mg differed; c (Å) value decreased, and a (Å) increased than of pure LiNbO 3 . The influence of dopants on the photoluminescence (PL) properties of the Er:Mg:LiNbO 3 single crystal fibers excited by laser lines of 514 nm was reported. Also, the PL properties according to temperature and the excitation power of Er:Mg:LiNbO 3 crystal fibers were analyzed.
