DYNAMICS OF A ND-DOPED FIBER LASER - CW AND SELF-PULSING REGIMES, STABILIZATION

The Nd-doped fiber laser can either operate in the continuous-wave reg ime or display undamped spiking. In the first case, most of the phenom ena may be interpreted in the framework of model of a two-mode laser, in which each mode is associated with one polarization eigenstate. In the situation for which the output becomes spontaneously periodic or c haotic, we present the observed regimes and optical spectra. Then, we propose and check experimentally a feedback technique for suppressing these oscillations.
