We present an experimental study of self-pulsing characteristics of a high-power single transverse mode Yb-doped double-clad continuous wave (CW) fiber laser. The self-pulsing features under high-power single-end pumping and double-end pumping configurations have been shown to be distinct. Our experimental observation indicates that in single-end pumping configuration, self-pulsing is predominant due to saturable absorption effect, caused by the weakly pumped portion of the fiber at the farther end. However, in double-end pumping configuration, uniform pumping and hence gain uniformity along the fiber length avoids the onset of saturable absorption of signal along the fiber length and thereby reduces self-pulsing, which finally results in a much more stable output.
