摘要: In this paper, the chaotic behaviors in an erbium-doped fiber (EDF) single-ring laser (EDFSRL) are investigated experimentally by using the loss modulation method. An electro-optic modulator (EOM) made of LiNbO3 crystal is added to the system. Thus, by changing the modulation voltage and the modulation frequency of the EOM, the freedom of the EDFSRL system is increased. The chaotic characteristics of the system are studied by observing the time series and the power spectra. The experimental results indicate that the erbium-doped fiber single-ring laser system can enter into chaos states through period-doubling bifurcation and intermittency routes.
