High-power laser/optical-fiber-coupling device - DeepDyve
A compact optical system for coupling high-power laser radiation (Nd:YAG) to optical fibers is described.. Graded-index optics (GRIN rod) have been used because of their characteristics, such as small dimensions, plane and parallel faces with focus near the exit face, which make them suitable for fiber components.. A special coupling unit to connect the microlens with the fiber has been designed ..
