Erbium doped LiNbO 3 (Er:LiNbO 3 ) single crystal fibers were grown free of cracks along c‐axis by the micro‐pulling down (μ‐PD) method. We have investigated the up‐conversion property with the change of doped Er 2 O 3 concentration and the starting melt composition. An enhancement of green upconversion according host matrix is also observed the stoichiometric LiNbO 3 . And, the dependence of the green emission according to Er 3+ concentration is analyzed. The possible application of the Er 3+ doped stoichiometric LiNbO 3 single crystal fiber for up‐conversion based optical devices is discussed.
