Abstract
An optical fiber tip for use in a laser delivery system comprising a distal end of an optical fiber having an exposed cylindrical core. A flat elliptical surface is formed across a distal end of said cylindrical core and intersects a center line of said cylindrical core at a predetermined angle. In one embodiment, a reflective coating is deposited on said flat elliptical surface such that a laser beam carried by said fiber will be reflected by said reflective coating. In another embodiment, said flat elliptical surface intersects said center line of said cylindrical core at an angle exceeding a critical angle necessary for said flat elliptical surface to totally reflect a laser beam carried by said optical fiber.
