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.

Abstract:

RF excited gas laser consists of a laser tube having external surfaces; a power supply compartment having elongated external fins and a pair of endplates on its opposite ends and wherein laser tube is placed between and is flexibly attached to the endplates; a sheet-metal cover mounted to the endplates and to power supply compartment and forming a laser assembly and having at least one pair of intake openings and at least one pair of exhaust openings for the cooling air to flow through the laser assembly by entering the laser assembly through the intake openings and flowing over power supply external fins and over laser tube external surfaces and then exiting through the exhaust openings. Present invention is characterized by lower cost and more efficient forced air cooling laser tube and RF power supply.
