摘要： An optical collimator system for a high power fiber laser system that collimates the individual light beams amplified by a plurality of fibers in the laser system. The fibers are optically coupled to undoped fibers and the fibers are optically coupled to one surface of an optical substrate. A registration guide precisely aligns the fibers to the substrate. Lenses are optically coupled to an opposing surface of the substrate in precise alignment with the optical fibers. The light beam from each fiber propagates through the substrate and diverges, and the associated lens collimates the beam to have a desired beam width and direction. Each lens includes an anti-reflective coating so that the optical beam from the fiber is not significantly reflected back through the substrate.

摘要翻译： 一种用于高功率光纤激光系统的光准直仪系统，该系统使由激光系统中的多根光纤放大的各个光束准直。 光纤被光学耦合到未掺杂的光纤，并且光纤被光学耦合到光学基底的一个表面。 配准指南精确地将纤维与基材对齐。 透镜与光纤精确对准地光学耦合到衬底的相对表面。 来自每根光纤的光束传播通过衬底并发散，并且相关的透镜使光束准直以具有期望的光束宽度和方向。 每个透镜都包含防反射涂层，以便来自光纤的光束不会明显反射回来。
