ABSTRACT:
The invention is directed to a method of making ring laser resonator blocks according to the sandwich principle. Channel and hollow chamber structures are machined into two plates of a multiple expansion of a resonator block. The structures in the blocks complement each other. The plates machined in this manner are placed one atop the other and positioned in correspondence to the structures and joined to each other and thereafter separated into individual resonator blocks.
