Self-pulsing in Er3+-doped fibre laser
TLDR
In this article, the output intensity of an erbium-doped fiber laser was studied with three pumping wavelengths: 514.5 nm, 810 nm and 980 nm.Abstract:
The output intensity of an erbium-doped fibre laser was studied. Experiments were performed with three pumping wavelengths: 514.5 nm, 810 nm and 980 nm. The laser output intensity exhibits three different dynamical behaviours: steady-state, sinusoidal variation or self-pulsing. In particular, in a bad (high-loss) cavity configuration, when the pumping ratio is increased above the lasing threshold the output intensity changes continuously from a steady-state to an infinite train of pulses. We also show that, depending on the cavity configuration, the transient oscillations display different forms.read more

Effects of ion pairs on the dynamics of erbium-doped fiber lasers.
TL;DR: A linear stability analysis demonstrates the existence of self-pulsing for a finite range of pumping rates and a theoretical model which describes the active medium as a mixture of isolated ions and ion pairs is presented.

Influence of ion pairs on the dynamical behaviour of Er3+-doped fibre lasers
TL;DR: In this article, the influence of ion-pair concentration on the dynamical behaviour of erbium-doped fiber lasers was demonstrated. But the authors focused on the effect of ion pair density on the output of the laser and showed that the output intensity evolves continuously from an infinite train of pulses to a CW steady state as the pumping ratio increases.
