Abstract
A high energy laser-to-fiberoptic waveguide coupling method and apparatus is disclosed for optically coupling substantially all of the beam of a high energy laser into a small diameter optical fiber. High energy lasers often generate beams having cross-sectionally non-uniform energy densities. The coupling apparatus includes an optical fiber segment located between the laser and the small diameter optical fiber, for receiving substantially all of the non-uniform beam and for transforming it into a circular cross-section beam of uniform energy density. Substantially all of the uniform beam is directed into the small diameter optical fiber.
