Abstract

A ring laser gyro having a triangular-shaped block design (10) includes a cathode (24,26) on each side leg of the triangular-shaped block and one anode (28) on the base leg of the triangular-shaped block. Furthermore, the anode (28) is connected via connecting bores (36,38) to gas reaming bores (30,32) in the corner points of the block in order to pass away ions and electrons of the plasma from mirrors (18,20) arranged in the corner points of the block.
