Abstract
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.
