Study of hyperchaos resulting from an erbium‐doped fibre three‐ring laser system

A novel erbium-doped fibre three-ring laser system with a ring-coupled-ring-coupled-ring to obtain dynamic behaviours and develop theoretical model of is presented. Our studies on the an are reported. The exhibits hyperchaotic chaotic behaviours, as well coexistent scenarios showing routes from period-doubling chaos, by shifting pump levels. results can be used reference value for emitter technology applications.
