Abstract: A cladding stripper includes a plurality of transversal notches or grooves in the outer surface of an exposed inner cladding of a double clad optical fiber. Position and orientation of the notches can be selected to even out cladding light release along the cladding light stripper, enabling more even temperature distributions due to released cladding light. The notches on the optical fiber can be made with a laser ablation system.
Abstract translation: 包层剥离器在双包层光纤的暴露的内包层的外表面中包括多个横向凹口或沟槽。 可以选择凹口的位置和取向以均匀地包覆沿着包层光剥离器的光释放，由于释放的包层光而能够实现更均匀的温度分布。 光纤上的凹口可以用激光烧蚀系统制成。

Abstract: An optical delivery waveguide for a material laser processing system includes a small lens at an output end of the delivery waveguide, transforming laser beam divergence inside the waveguide into a spot size after the lens. By varying the input convergence angle and/or launch angle of the laser beam launched into the waveguide, the output spot size can be continuously varied, thus enabling a continuous and real-time laser spot size adjustment on the workpiece, without having to replace the delivery waveguide or a process head. A divergence of the laser beam can also be adjusted dynamically and in concert with the spot size.
Abstract translation: 用于材料激光处理系统的光学传输波导包括在传送波导的输出端处的小透镜，将波导内部的激光束发散转换成透镜后的光斑尺寸。 通过改变发射到波导中的激光束的输入会聚角和/或发射角，可以连续地改变输出光斑尺寸，从而能够在工件上进行连续且实时的激光光斑尺寸调节，而无需更换 输送波导或过程头。 也可以动态地调整激光束的发散度并且与光斑尺寸一致。
