High Power Fiber Optical Components

Optical Fiber End Cap

The fiber end cap increases the beam size as the laser exits the fiber end. It reduces the power density at the interface between fiber and air offering much higher transmitted power from fiber cores in a miniature format. Based on Our beam shaping technology, a high-quality end cap is uniquely formed directly at the fiber tip that transmits uniformly beam spot. We use both fusion splicing and thermal expansion to produce end cap optimized for various applications. Polarization maintains fiber end cap is our specialty. The end cap diameter coreless rod selection is to maximize the out beam diameter. The length selection of the end cap is sufficiently shorter to avoid beam distortion from the edge.
