A cathode for a laser generator comprised of a monolithic body consisting essentially of an agglomeration of oxidized metallic particles.
A cathode for a laser generator comprised of a monolithic body composed of an agglomeration of a powder consisting essentially of oxidized metallic particles.
A laser generator comprising:
- a body for containing a gas;
- an electric potential source;
- an electrode in communication with said gas, said electrode secured to said body with a gas tight seal, said electrode being adapted to be electrically connected to a negative side of said source;
- and
- wherein said electrode is substantially composed of a monolithic body consisting essentially of an agglomeration of oxidized metallic particles.
A laser generator comprising:
- a body for containing a gas;
- an electric potential source;
- an electrode secured to said body a gas tight seal, said electrode being adapted to be electrically connected to a negative side of said source;
- and
- wherein said electrode is a monolithic body composed of an agglomeration of a powder consisting essentially of oxidized metallic particles.
A method for making an electrode for engagement with a laser housing comprising the steps of:
- forming a selected electrode body structure of a powder consisting substantially of oxidized particles of at least one metal;
- and
- heating said electrode structure for a sufficient time to cause said powder to bond together to form a monolithic body and which infuses high compressive and mechanical strengths, has high temperature stability, and low permeability to a gas, does not exhibit out-gassing, and is resistant to oxidation.
A method for making an electrode for engagement with a laser housing comprising the steps of:
- machining a monolithic body consisting substantially of oxidized particles of at least one metal to form a selected electrode body structure;
- mounting said electrode body to said laser body;
- and oxidizing said electrode structure.
