高功率1018nm连续掺镱光纤激光器

High power 1018 nm continuous wave ytterbium-doped fiber laser

成功搭建了高功率1018 nm连续掺镱光纤激光器,通过合理地择增益光纤长度,有效地抑制了ASE。实验获得了300 W最高输出功率,斜率效率为81%。

A high power 1018 nm continuous wave ytterbium-doped fiber laser was presented. The relationship of laser threshold power and gain fiber length in YDF was simulated and analyzed,and amplified spontaneous emission （ASE） is suppressed effectively by appropriately selecting length of YDF. The 1018 nm continuous wave laser output with a output of 300 W and a power conversion efficiency of 81% is obtained when the pumping power is 370 W.
