Fiber delivery system for laser diodes

摘要

An optical fiber delivery system comprising a number of first optical fibers, preferably in a bundle, and a second optical fiber light from a number of light sources are coupled into the second fiber via the first fibers. The emitting diameter of the first fibers is adjusted to match the core diameter and acceptance angle of the second fiber by reducing/increasing the number of emitting light sources being coupled to the first fibers. Thereby the brightness and efficiency of the light beam is preserved throughout the entire system in particular when the beam is passed from the first fibers to the second fiber, even if the power is reduced or the diameter of the second fiber is very small. Accurate knowledge of the optical beam which is eventually emitted by the second fiber is obtainable. Further, a method for delivering optical power from a number of light sources using the fiber delivery system.
