Self-Starting Mode-Locked Erbium-Doped Fiber Laser |

Abstract: | By using the nonlinear switching effect of nonlinear optical fiber loop mirror (NOLM) and the saturable absorption effect of bulk semiconductor waveguide self-staring mode-locking of erbium-doped fiber laser has been demonstrated. High stable mode-locked pulses train has been obtained. Harmonically mode-locked pulses have been observed. The nonlinear switching reflection characteristic of NOLM is analyzed. |
