Abstract

In this paper, numerical analysis was investigated for the double-clad fiber lasers and experimental study on the Yb³⁺-doped double-clad fiber lasers was performed. The results shown that the output power increased monotonically with absorbed power, and in lossy cavity the output power is less than in the lossless cavity. The output power decreases for the lossy fiber with the reflectivity of output coupler. There was an optimum fiber length to reach a maximum output and the optimum length was mainly dependent on the loss coefficient. In experiment we obtained an output power of 21.6W, slope efficiency of 54% by using Yb³⁺-doped double-clad fiber and 40W LD pump source.
