Abstract

We report the observation of self-pulsing behavior in a linear cavity Er-doped fiber laser pumped by a 980 nm laser diode. Stable self-pulsing is observed for both continuous-wave and low frequency chopped pumping. By measuring the time evolution of the transmitted pump light, we were able to observe a long build-up time (around 5 ms) for lasing action to take place. While the self-pulsing behavior of similar lasers has been recently reported, the long laser build up times have not been reported before. A numerical model for the time and space dependance of the excited state populations of the Er-ions reproduces some of the observed features.
