For the first time, a quaternary doping system of Er3+, Yb3+, Ce3+, Na+:CaF2single crystal was demonstrated to have high fluorescence yield in the eye-safe 1.5μm region under 980nm laser diode pumping, with relatively broad and flat gain curves. A simplified model was established to illustrate the effect of Ce3+on the branching ratio for the Er3+4I11/2→4I13/2transition. With 0.2-at.% Er3+and 2.0-at.% Ce3+in the quaternary-doped CaF2crystal, the branching ratio was estimated to be improved more than 40 times by the deactivating effect of Ce3+on the Er3+4I11/2level. The quaternary-doped CaF2system shows great potential to achieve high laser performance in the 1.5μm region.
