Paper Abstract

We describe the lasing behaviour of an all-fibre laser with saturable absorber with emphasis on observed hysteresis and bi-stable dynamics for certain parameter regimes. The fibre laser is a simple Fabry Perot cavity with Erbium and thulium doped sections that provide optical gain and saturable absorption respectively. We explore methodically laser behaviour for consecutive up and down scans of optical pump powers for up to 13 unique experimental configurations using different lengths of the absorber section (ranging from 0.21 m to 1.48 m). We report interesting bistable behaviour as well as hysteresis which exists for a narrow range of saturable absorber lengths(0.66 m to 0.78 m).
