Abstract

In this paper, we demonstrated a 2815-W bidirectonal side-pumped DSCCP fiber master oscillator power amplifier (MOPA) configuration within the 250 μm cladding fiber, with the slope efficiency of 77.8%. And the output power is limited by the pump power. As we know, it is very difficult to get multi kW output power in 250μm general double cladding fiber. If a two cascaded amplifiers is employed, a 6 kW output power can be expected.
