Optical fibers in the ribbon geometry have the potential to reach powers well above the maximum anticipated power of a circular core fiber. In this paper we report the first doped silica high order mode ribbon fiber oscillator, with multimode power above 40 W with 71% slope efficiency and power in a single high order mode above 5 W with 44% slope efficiency.
带状结构的光纤有潜力达到远高于圆形芯光纤预期最大功率的功率。在本文中，我们报道了首个掺杂二氧化硅高阶模带状光纤振荡器，其多模功率超过40瓦，斜率效率为71%，单高阶模功率超过5瓦，斜率效率为44%。
