In order to study the dynamical behaviors of self-Q-switched erbium-doped fiber lasers, all-fiber self-Q-switched erbium-doped fiber lasers with linear cavity configuration and ring cavity configuration were constructed. Theoretical analysis and experimental verification were also carried out. In the experiment, when pump power reached the threshold, output laser was observed by oscilloscope with the increase of pump power. Linear cavity laser output experienced two operation states of continuous wave (CW) and self-Q-switched in turn and failed to appear CW operation state again because of the constraint of pump power. Ring cavity laser output experienced self-Q-switched operation state at first and then CW operation state. For linear cavity, self-Q-switched pulses can be obtained with pulse width from 8s to 100s and repetition rate from 2.5kHz to 54kHz in pump power range from 21mW to 190mW. For ring cavity, self-Q-switched pulses can be obtained with pulse width about 165s and repetition rate about 3kHz at pump power range from 16.2mW to 110mW. The results show that dynamical behaviors of output laser are different because cavity configurations of self-Q-switched erbium-doped fiber laser are different. Although both linear and ring cavities have self-Q-switched pulse output, the range of self-Q-switched pulse is wider for linear cavity.
