Abstract

Because an ytterbium-doped fiber amplifier has broad-gain bandwidth, high output power, and excellent power conversion efficiency, it has attracted much attention. Based on two-level model, the gain and propagation characteristics of Yb-doped fiber amplifier at 1064nm by dual-wavelength pumping (910nm and 975nm) were analyzed after introducing the overlapping factors and ignoring the effect of ASE and the fiber loss. In order to compare, other two pumping schemes were discussed, namely, 910nm pumping and 975nm pumping respectively. The differences between the Yb- and Nd-doped fibers for amplifying the light of 1064nm were also discussed.
