ABSTRACT:
A method for attaching a diamond component to metal is described, wherein a layer of brazing material is provided at the interface between the diamond and the metal. A laser is used for heating the brazing material. The laser beam is focussed through the diamond at least substantially on the interface between the diamond and the metal. In one aspect, the invention is utilized in the manufacture of a travelling wave tube having a metal helix disposed within the tube. Diamond support blocks are bonded between the inner walls of the tube and the windings of the helix according to the method of this invention.
