Ring-cavity Er/Yb co-doped fiber laser and its mode characteristics
A ring-cavity Er/Yb co-doped fiber laser (EYDFL) was designed and the characteristics was studied in this paper.It used 1064nm Nd:YAG laser as its pump, and the gain medium is a 4.1m-long EYDF. The single longitudinal-mode operation is realized by introducing a fiber Bragg grating (FBG) as narrow wavelength-selective element, and a section of EDF not-pumped as saturable absorber. The fiber laser resonator has been optimized, and the stable laser output with single longitudinal-mode was got. In the simulation and experimental study, the difference of fiber laser output power using output coupler in different coupling ratio has been studied. The optimal coupling ratio testified in experiments was near 80 percents. The effects and influences of saturable absorber on characteristics of output laser mode are analyzed.
