Model of the self-Q-switching instability of passively phased fiber laser arrays
Abstract
A simple physical model is presented to explain observed self-pulsations in passively phased rare earth-doped fiber laser arrays. Their essential features are the feedback level s sensitivity to small perturbations in the phases of array fields, hence altering the cavity s Q-value, and the nonlinear changes in the refractive index of the amplifier gain media. The model s qualitative prediction for an array having at least two elements that is operated at sufficiently high power levels, of the growth of an initial disturbance, is confirmed by a linearized stability analysis of the field and medium equations.
