A 1-WATT THULIUM-DOPED CW FIBER LASER OPERATING AT 2-MU-M

[摘要] We report efficient high power (> 1 W) single transverse mode continuous-wave laser action at 2-mu-m in a thulium-doped silica-based fibre laser pumped by a Nd:YAG laser at 1.064-mu-m. The highest measured output power was 1.35 W. A threshold of 600 mW absorbed and slope efficiency of 37% with respect to absorbed power were observed.
