Claims
- 1. A process of making a gas laser apparatus comprising the steps of:
- selecting an optical mirror blank;
- making a metal mirror blank support ring having an opening therethrough for mounting the selected mirror blank thereon and having a heat expansion rate generally matching the heat expansion rate of said optical mirror blank;
- applying a glass frit material between the mirror blank and the mirror blank support ring, said glass frit having a heat expansion rate generally matching the heat expansion rate of said optical mirror blank and metal mirror blank support ring;
- heating the mirror blank and the metal mirror blank support ring and glass paste material thereon to a temperature in excess of 400 degrees centigrade in a nitrogen atmosphere to seal said mirror blank to said metal mirror blank support ring with a glass frit seal;
- attaching said mirror blank support ring having the mirror blank attached thereto to a temperature expansion sleeve of a gas laser assembly to thereby form a laser with a high temperature glass to metal seal for the mirrors in a gas laser; and
- vacuum baking the laser assembly at approximately 300 degrees centrigrade for at least twenty-four hours to remove moisture and impurities therefrom.
- 2. A process of making a gas laser apparatus in accordance with claim 1 including the step of selecting a waveguide material and, optical assembly support rods for a temperature expansion of approximately the same expansion as the temperature expansion sleeve whereby opposite expansion of the temperature expansion sleeve with offset the ceramic waveguide and optical assembly support rods temperature expansion.
- 3. A process of making a gas laser apparatus in accordance with claim 2 including the steps of selecting a metal mirror blank supporting ring of carpenter's metal and an optical mirror blank of zinc selenide and a silica seal glass paste for heating to a temperature of approximately 440 degrees centigrade and the welding the metal mirror blank supporting ring to a kovar temperature expansion sleeve.
