A novel design of multi-mode Er-doped fiber lasers operated in the spectral region of 1530-1600 nm have been proposed and realized. The lasers efficiency exceed 35-42% (depending on the wavelength), while maximum output power is limited on the level of 60 W only by pump power available in the experiment. The developed multi-mode laser can be used as an efficient high-power and high-brightness pump source for Erdoped (pump at 1530-1535 nm) and Tm-doped (pump at 1560-1600 nm) singlemode fiber lasers. Utilization of the same concept to the Yb-doped lasers could strongly accelerate output power growth of single-mode lasers in the 1 μm region as well.
