A new type of monolithic high-power fiber laser with a multifiber series and distributed pumping is put forward. The distributed pumping multifiber series fiber laser is a good solution to scale up laser output when injection power is limited by the output powers of a pigtailed laser diode or the maximum sustainable powers of pumping couplers. The simulation results show that the laser has advantages of high transfer efficiency and good temperature uniformity in the kilowatt power domain.
