Abstract: Systems and methods for fabricating capacitive discharge electrodes for a ring laser gyroscope are disclosed. In one example, a laser block for generating a laser in a closed loop path comprises a laser block, wherein an optically closed loop path is formed within the laser block. Additionally, at least two electrodes are formed on the laser block, wherein the at least two electrodes are used in conjunction with a radio frequency power supply to create an electric potential in the laser block which generates at least one laser beam in the closed loop path. The at least two electrodes are manufactured by placing a paste composition on the laser block and securing the paste composition to the laser block. The paste composition also includes a conductive material.
