A method of making a hollow waveguide for transmitting electromagnetic radiation includes: filling voids on the inner surface of an insulator tube with a coating of a void-filling, hydrophylic material having a free pair of electrons and capable of complexing metal ions; applying a solution of a metal salt over the void-filling material to form a metal complex with the void-filling material; reducing the metal complex to a pure metal layer; and depositing a dielectric film on the pure metal layer.

Method of making hollow waveguides

A hollow waveguide for guiding laser energy, includes a proximal end for receiving the laser energy and a distal end terminating in a distal tip for delivering the laser energy to a working area. The distal end of the hollow waveguide includes an annular, converging, inner surface converging the laser energy towards the distal tip such as to concentrate the laser energy delivered through the distal tip to the working area. Also described are methods of making the hollow waveguide.

Hollow waveguide tips for controlling beam divergence and method of

A laser beam waveguide particularly useful for transmitting infrared laser radiation includes a flexible, hollow plastic tube; a metal layer on the inner surface of the hollow plastic tube; a thin dielectric film on the inner surface of the metal layer; and a flexible layer over the outer surface of the hollow plastic tube capable of absorbing infrared radiation and preventing kinking of the hollow plastic tube.
