In the paper, a 3 µm mid-infrared (MIR) high energy ultrafast Er:ZBLAN fiber laser and amplification system is presented. The 3µm seed pulses were generated through an Yb-doped ultrafast fiber laser pumped optical parametric amplification (OPA). A pulse energy of 12.4 µJ is generated at a repetition rate of 100 kHz with a pulse duration of 103 fs. A Er:ZBLAN fiber amplifier was used to further boost the chirped pulse energy to 84 µJ.
