Nd: YAG Laser Power Transmission through an Optical Fiber

This article describes characteristics of Nd: YAG lasers and the technologies of beam delivery through flexible optical fibers. The spread of the industrial YAG laser market has been accelerated by the enhancement of laser power and by the utilization of flexible optical fibers for beam delivery. New methods of bothbeam division and beam addition are developed by using fiber beam delivery technologies . Fiber power transmission enables the use of high power YAG lasers for new applications in extremely severe environments such asthe interior. of thin pipes or underwater.
