The Bi-doped fiber lasers operating at wavelengths of 1280 nm, 1330 nm, 1480 nm, and 1500 nm with a maximal output power of up to 2 W and a slope efficiency of 14 -25% have been demonstrated for the first time. We have also investigated the influence of the doping concentration (GeO2 and P2O5) on th
