The Coherent NuBEAM multi-mode, step index beam delivery fibers are designed for solid-state, fiber and diode laser systems. Benefiting from an environmentally controlled facility and many years of experience, the engineers at Coherent have developed a new generation of beam delivery fibers designed to address the laser industry’s ever increasing need for greater power handling capability. NuBEAM fibers are available in a large assortment of core and clad diameters accommodating the widest range of applications. NuBEAM power delivery fibers are offered with silicone, transparent nylon, and tefzel buffers. They are also available with Nufern’s proprietary NuCOATFA coating for added power confinement and polyimide for high temperature applications. NuBEAM fibers are biocompatable and are ISO 13485 compliant.
