Abstract

The 2.7 μm emission has been obtained using 980 nm laser excitation in Er3+/Tm3+/Pr3+ triply doped ZrF4–BaF2–LaF3–AlF3–YF3 glass. 2.7 μm emission characteristics and energy transfer are investigated. Population inversion between the 4I11/2 and 4I13/2 levels is significantly enhanced by way of Tm3+ and Pr3+ co-doping into Er3+-doped fluoride glass. These results indicate that this Er3+/Tm3+/Pr3+ triply doped fluoride glass has potential applications in 2.7 μm laser.
