Fiber End Caps for High Power Fiber Lasers and Amplifiers

Fiber End Caps are essential optical components designed for end-face processing in fiber lasers and fiber amplifiers. They are specifically engineered to handle high average power at the interface of glass and air. By extending the cross-sectional area at the end faces of fibers, fiber end caps help enhance the output power limit of fiber lasers. This extension reduces the power density at the terminals, thus preventing damage caused by intense heating and scorching.
