碩士 === 國立交通大學 === 光電工程所 === 89 === In this thesis we study a polarization APM mode-locked Er-fiber laser both experimentally and theoretically. In the experimental side, we have successfully built a self-started mode-locked Er-fiber laser that can produce a stable pulse train with a 19.67 MHz repetition rate and a 2.4 mW average output power. The observed pulse duration is around 1.6 ps. In the theoretical side we have simulated the fiber laser by solving the dynamic equation of the laser derived from a variational method. From our simulation we can show the existence of pulse compression mechanism and obtain a stable laser pulse output.
