            Abstract : 
An Er3+-doped ZBLAN fiber amplifier for Q-switched pulses at 2.79 μm is reported. Over 24 μJ of pulse energy at an average output power of 1.0 W was achieved at a maximum available pump power of 9.4 W. The efficiency of this pulsed laser fiber amplifier is about 10%. Our simulation predicts that over 300-μJ pulses can be achieved with this fiber amplifier when a 120-W pump is used.
