## Abstract A novel Er^3+^/Yb^3+^ coโ€doped doubleโ€clad fiberโ€ring laser, which utilizes amplified spontaneous emission as a secondary pump source in order to operate in Lโ€band, is demonstrated. Six laser diodes are used to claddingโ€pump Er^3+^/Yb^3+^ coโ€doped doubleโ€clad fiber. When the pumping pow
