    • A fiber optic structure for efficient pumping of a rare-earth element fiber laser, such as an Ytterbium fiber laser, operating at the three-level transition. In order to operate at the three-level transition, a large amount of pumping energy must be effectively coupled from the fiber's inner cladding into the rare-earth element-doped core. The present invention discloses the use of eccentric asymmetric, and non-cylindrical inner claddings to maximize the overlap of the pumping energy of multi-mode field distribution patterns with the fiber core and to maximize the number of intersections of the pumping optical ray trajectories with the core. While the cladding surrounding the core is eccentric with respect to the core, the core itself is coaxial with the outer cladding for compatibility in coupling to standard transmission fibers. Also disclosed is the use of air claddings and methods for optimal sizing of the capillaries. In addition, the creation of regions of differing index of refraction in the cladding is disclosed, to further enhance mode conversion of pumping energy.
    • 一种用于高效泵浦诸如镱光纤激光器的稀土元素光纤激光器的光纤结构,其工作在三电平转换。 为了在三电平转换中工作,必须将大量的泵浦能量从纤维的内包层有效地耦合到稀土元素掺杂的芯中。 本发明公开了使用偏心不对称和非圆柱形内包层来最大化多模场分布模式与纤维芯的泵浦能量的重叠,并使泵浦光线轨迹与 核心。 虽然围绕芯的包层相对于芯是偏心的,但芯本身与外包层同轴,以便与标准传输光纤耦合。 还公开了使用空气包层和方法来优化毛细管的尺寸。 此外,公开了在包层中产生不同折射率的区域,以进一步增强泵浦能量的模式转换。
