Widely Tunable Fiber Ring Laser with Narrow Linewidth and Fine Tuning Resolution Based on Laser Materials

Abstract:

We experimentally demonstrate a tunable fiber ring laser with narrow linewidth and fine tuning resolution based on Er³⁺-doped fiber(EDF) laser material. A tunable fiber Bragg grating(FBG) filter is used in the system as the frequency selecting element, and a stepping motor together with a single chip acts as the precise tuning mechanism. The fiber ring laser has a narrow linewidth of ~0.07nm, a tuning resolution of ~1.5pm/pulse, an output power of ~25 mW, and a slope efficiency of ~17.9%.
