    • Head-on laser shaping of optical surfaces on optical fibers, related assemblies and methods are disclosed. By “head-on laser shaping,” a laser beam is directed in a laser beam path collinear or substantially collinear to the longitudinal fiber axis of an end portion of an optical fiber. The end face of the end portion of optical fiber is exposed to the laser beam to laser shape a polished optical surface in the end face of the optical fiber. In this manner, the entire surface area of the end face of the optical fiber can be exposed to the laser beam during laser shaping, making it unnecessary unless desired, to rotate the optical fiber or laser beam during laser processing. The cross section energy distribution of the laser beam can also be controlled to laser shape an optical surface in the end face of the optical fiber of the desired geometry.
    • 公开了光纤上的光学表面的正面激光成形,相关组件和方法。 通过“正面激光成形”,激光束被引导到与光纤的端部的纵向光纤轴共线或基本共线的激光束路径中。 光纤端部的端面暴露于激光束,以在光纤的端面激光地形成抛光的光学表面。 以这种方式,在激光成形期间,光纤的端面的整个表面积可以暴露于激光束,除非需要,否则在激光加工期间使光纤或激光束旋转是不必要的。 也可以控制激光束的截面能量分布,以在所需几何形状的光纤的端面中激光地形成光学表面。
