Abstract

A ring laser gyro including two partial gas discharge paths in which by an electrode arrangement an opposite gas discharge is ignited. Outside of the discharge path between the electrodes (24,26) connected to the ignition voltage ion traps (40,42) are provided in order to prevent a gas discharge between those electrodes (FIG. 1).
