This paper reports a systematic experimental investigation on the dynamics in the low-frequency region in an erbium-doped fibre-ring laser with loss modulation.A rich variety of bifurcation is analyzed through the bifurcation diagram and structured with the concept of the winding numbers.The coexistence of multiple attractors and the crisis that appear in the saddle-node bifurcations,and an interesting structure of bifurcation which is similar to the bifurcations in high-frequency range,have been observed.
