Optical and spectroscopic data and calculations in support of an efficient 1.3µm amplifier in a Pr3+-doped cadmium mixed halide glass host are presented. It is found that the dominant parameter affecting the amplifier gain is the lifetime (325µm) of the Pr3+ 1G4 state. The long lifetime is the direct consequence of a decreased multiphonon decay rate in this low-phonon-energy glass host. Gain in excess of 30 dB for 100 mW pumping in low-loss fibres is predicted and for background loss of 1 dB/m gain figures are as high as 15-20 dB.
