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.

A method of making a plurality of laser gyro resonator blocks wherein each resonator block defines a closed loop path in which two laser beams rotate in mutually opposite directions for measuring angular velocities, each of the resonator blocks including two component parts sandwich joined to each other to define a resonator block with the closed loop path being defined by a plurality of tunnel segments interconnected to form an outline having a plurality of corners with respective resonator mirrors mounted at the corners, the method comprising the steps of:
- providing a first plate having a first flat surface subdivided by a plurality of imaginary lines into said first parts of respective ones of said resonator blocks;
- providing a second plate having a second flat surface subdivided by a plurality of imaginary lines into said second parts of respective ones of said resonator blocks;
