Abstract
A net gain of 20 dB at 2722 nm has been obtained in an Er3+-Pr3+ co-do ped fluoride fibre pumped at 800 nm. Co-doping the fluoride fibre with Er and Pr instead of doping with Er only improved the net gain of the optical amplifier made with this fibre and reduced significantly the pump power requirement. These improvements can be explained by the emp tying of the I-4(3/2) level of Er3+ towards the (3F3, 3F4) levels of P r3+.
