ABSTRACT:
A flexible hollow waveguide for high efficiency transmission of laser light, comprising: (a) metal cladding tube having interior surface; and (b) elongated bent ribbon of a substrate material; said ribbon having concave interior surface and convex exterior surface and first and second edges therebetween; said ribbon is positioned in said metal cladding tube; said interior surface of the metal cladding tube engaging the said convex exterior surface of the ribbon to hold said first and second edges together and to define an elongated seam therebetween; and (c) first metal layer on the said concave interior surface of the said ribbon; said first metal layer having a elongated discontinuity defined by the said seam; and (d) seamless light reflective second metal layer formed on top of the first metal layer; and (e) seamless light-reflectivity enhancing dielectric layer formed on top of the said second metal layer.
