Abstract
The density of the energy that is conducted within a fiber-optic waveguide is increased by means of an energy coupler at the input end of the optical fiber. This energy coupler comprises a fused or ground lens at the input end of a silica-based fiber. A second lens, preferably a plano-convex lens, focusses a large collimated laser beam to a point source. The lens at the end of the fiber is located at a distance greater than the focal length of the second lens, so as to receive light from the point source and couple it into the fiber.
