Characterization of a 10 W single-mode Er:Yb doped double-clad fiber laser

摘要

In this paper we investigate the properties of a 10 W double-clad Er:Yb doped fiber amplifier in two laser setups. It is firststudied an all-fibered continuous laser. A laser efficiency of 20 % is obtained with an output power of about 8 W for 40 Wpumping power. A passively mode-locked fiber laser is then built up. In the anomalous dispersion regime it is obtained asoliton crystal involving some hundreds of solitons. We demonstrate that the soliton crystal becomes unstable for higherpumping power resulting in its dislocation.
