Abstract
The temporal dynamics of an Er
3+ doped fiber laser shows various interesting modes of behaviours. In the transient regime, beating and antiphase phenomena
between two orthogonal state of polarisation can be observed, while the total intensity exhibits regular relaxation oscillations.
In the stationary regime a Hopf bifurcation appears leading the laser from a cw working mode to different self pulsed working
modes. Under a sinusoidal modulated pumping the temporal behaviour of the fiber laser exhibits a period doubling cascade leading
to chaos. A study of the influence of the laser parameters allow us to determine (in a reduce parameter spaces) a bifurcation
diagram showing the boundary between the different working modes.
