A novel high gain rare earth ions co-doped fluoride phosphate fiber core material was designed. The influence of different component on system performance was studied, which was the key factor to prepare an optical fiber material with good thermal stability and high transmittance and non-crystallization. This fiber material has a high absorption cross-section (2.075 pm2), high emission section (1.11 pm2), long fluorescence lifetime (7.30 ms) , and high gain coefficient (74.099×103 pm3). These good parameters indicate that the designed material is suitable for preparing excellent optical fiber amplifier material with high gain and wide bandwidth.
