Abstract
When coherent light is amplified by a synchronous Raman fiber amplifie r pumped by output pulses from a high-power erbium-doped fiber amplifi er operating in an unsaturated gain regime, the detection efficiency w ith the heterodyne method is degraded. This degradation is caused main ly by cross-phase modulation effects. It is confirmed that using power -flattened pump pulses can suppress these effects. (C) 1997 Optical So ciety of America.
