Claims
- 1. In a high temperature laser, a feed-through assembly comprising:
- an open-ended elongated tubular quartz envelope,
- a first and second molybdenum assembly sealed to either end of said quartz envelope to seal off the enclosed volume of said quartz envelope, said first molybdenum assembly including an electrical contact means for connection to an electrical excitation source, said second molybdenum assembly including an electrode adapter means and
- a tubular electrical conductor means positioned within said quartz envelope and connected between said electrical contact means of said first molybdenum assembly and said electrode adapter means of said second molybdenum assembly.
- 2. An assembly as claimed in claim 1 wherein said tubular electrical conductor means is molybdenum.
- 3. An assembly as claimed in claim 1 wherein the sealed-off enclosed volume of said quartz envelope is evacuated.
- 4. An assembly as claimed in claim 1 further including an inert gas within the sealed-off enclosed volume of said quartz envelope.
- 5. An assembly as claimed in claim 1 wherein quartz to molybdenum mechanical press seals seal the first and second molybdenum assemblies to said quartz envelope.
- 6. An assembly as claimed in claim 1 wherein tubular electrical conductor means consists of tubular molybdenum rod and a tubular bellows element to provide thermal expansion compensation.
- 7. An assembly as claimed in claim 1 wherein said first and second molybdenum assemblies are cup-like members, said electrical contact means being positioned at the center of the base of the first molybdenum cup-like member, said electrode adapter means being positioned at the center of the base of the second molybdenum cup-like member, said tubular electrical conductor means being a molybdenum rod concentrically positioned within said quartz envelope.
