    Abstract: In accordance with the present invention, there is an optical amplifier fiber comprising a core manufactured from a phosphate glass doped with a rare earth element and a cladding manufactured from a phosphate glass surrounding the core. The core has a radiative lifetime in the range of 7 to 9 milliseconds at 1535 nm, a fluorescence lifetime of greater than 7.5 milliseconds at 1535 nm. The optical amplifier fiber has a diameter ratio in the range of 0.036 to 0.044, a transformation point difference of the core and the cladding, measured in (°C), less than 5%. Further, the optical amplifier fiber has a coefficient of thermal expansion, measured in (/°C), difference between the core and the cladding is less than 2% and an absorption cross section in the range of 0.60 x 10 -24 m2 to 0.72 x 10 -24 m2, in the range of 1530 nm to 1540 nm.
