Abstract

This paper proposes and verified a modified cavity configuration in oscillating-amplifying integrated fiber laser for stimulated Raman scattering suppression. A short segment of YDF and a long piece of GDF is used in the oscillating section, which can simultaneously suppress the onset of Raman component and avoid the self-pulsing operation caused by the extremely low gain in cavity. Experimental result shows a 31dB Raman suppression ratio at 1080nm when output power reaches 5kW without any other Raman suppression element.
