ABSTRACT:
A gas laser apparatus includes a ceramic wave guide having a bore extending therethrough and a pair of slots formed in the exterior thereof with electrodes formed in the slots. An optical assembly is mounted on each end of the waveguide and includes a mirror which is attached to a metal ring in the optical assembly where they harden a fused glass frit material. A plurality of invar metal rods connects the optical assemblies and has adjustment screws on each end of each rod for tilting a portion of the optical assembly on a metal flexure member to align the mirrors. The tubes and rods in the optical assemblies holding each mirror have temperature compensating materials and sizes to maintain the mirror in alignment, and separation over wide ambient and operating temperatures.
A process of making a gas laser includes 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 therein, applying a glass paste material between the mirror blank and the mirror support ring, heating the mirror blank and the mirror blank support ring and glass paste material to a temperature in excess of 400 degrees centigrade to seal the mirror blank to the metal mirror blank support ring with a glass frit seal, and then attaching the support ring to a laser optical assembly on each end of a laser assembly.
