Abstract : The paper reports on analysis of the dyn amics and operation stability of pumping sem iconductor lasers of optical fiber amplifiers in optical eornmunication systems. The parameters of the amplifier system that correspond 10 stable operalion and low intensity noise arc explored. The study is based on a time-delay model of the rate equations of the photon number, optical phase and the injected electron number. The analyses are performed in terms of the instantaneous fluctuations of the laser intensity, the corresponding bifurcation diagram and phase portraits. and the relative intensity noise, The frequency spectra of the intensity noise under strong feedback are characterized . The results indicate that the laser stability improves when the length of the external cavity formed between the laser and a fiber grating decreases where the laser operates almost in either pulsation or cont inuous wave. The operation becomes almost chaotic interrupted by narrow regi ons of continuous wave in the extreme of long external cavities, which degrades the laser stahiliry.
