ABSTRACT:
A process for producing a fluidtight seal between a body of a vitroceramic material and a metal element intended to be part of the construction of a gas laser and in particular a laser gyrometer includes interposing between the surfaces of the body of vitroceramic material and the metal element to be sealed a joining member of a metal capable of diffusing into the vitroceramic material, and subjecting the assembly thus formed to a thermo-compression operation so as to result in a superficial diffusion of the material of the joining member into the facing surfaces of the body of vitroceramic material and the metal element.
